1169: Xander Perrott’s “Conglomerate”

| wonko

Multi-unit Kusudama folding is something I enjoy – the emergent geometry and intricate interlocking of units to make a whole is very satisfying. None more than “Conglomerate” designed by Xander Perrott:

When I saw his fold on insta I knew I wanted to fold it – I had not seen anything quite like it, so I reached out to Xander and he shared instructions – how wonderful is the internet?

Let’s break this down – the kusudama is composed of 30 units, each folded from a rectangle in the proportions of 1: sqrt(3). Each unit has a triangle grid imposed on it, with triangular gussets to allow the “facets” of the faces to become 3D.

The geometry of the unit is very pleasing to fold, it all feels really natural, and the tiny collapse of the unit to make it 3D also feels right.

Interlocking the units …. now that seems to have taken me an age – each unit cups around one lobe and inside another lobe, forming a many-layered, staggered icosahedrons – each locked into place at multiple anchor points. It took me a while to master the locking process, then re-learn it as the orientation turned this way and that, but this kusudama needs no glue, and when a unit is fully locked in it is really rigid and strong.

1167: Aye Aye

| wonko

Primates are a diverse collection of animals that contain us hominids, apes and a variety of “monkey-like” critters. One of the most primitive, obscure and endangered is a type of Lemur, native to Madagascar, called the Aye Aye:

Largely nocturnal, and generally feared because of it’s slightly crazed appearance and creepy long fingers, apparently it uses its fingers to reach into decaying wood to pluck out juicy grubs – yum. I had never seen anything like it rendered in origami until I was proofing a soon to be published book by Kunsulu Jilkishiyeva titled “Origami Oddities”. I knew I had to try it.

Using a 45cm square of Damul Kraft (from Origami-shop) in brown/natural, the pre-creasing was fairly straight forward, the first collapse is complex (an “everything at once” style collapse I love). Isolating the features is pretty straightforward, but this is not a beginners fold, it contains some deliciously complicated maneuvers.

WM02 – An Art Piece?

| wonko

Those following my socials will have seen that i was quite excited with an idea and it’s execution – a rare 1-2 whammy with me:

Having made Mulberry Washi, I was trying to decide what i wanted to do with it. I think the larger sheets are currently sheet pulp storage I will re-beat and incorporate into other sheets, but sheets 1 and 2 (names WM01 and WM02 – my nomenclature) I wanted to keep…because.

WM01 is barely there mulberry tissue – I will not fold it, but it is fascinatingly strong. WM02 on the other hand is almost a sheet of paper – thin, lovely deckle edges and loads of character.

I had this idea, based in part on my extensive folding from one of the oldest origami books there is – Senbaruzu Orikata. The idea of a traditional Tsuru (crane – the one everyone including me learns first) still connected by a wing-tip to the surrounding paper began to eat away at me (originally the idea woke me up).

Folding connected cranes is all about the prep, so as not to put too much strain on the part that joins – a single point of failure. Exploring the sheet, I searched my origami squares collection and found that an 11.7cm square could be placed, avoiding the holes and weirder bits, so decided on that size arbitrarily. I also liked how much of the sheet would be untouched, and reasoned I would need it to attach to a backboard if it were to be framed… but I am getting ahead of myself – I had no idea if I could fold or work the sheet at all.

In pencil, I traced the square as accurately as I could, then carefully with a scalpel liberated all 4 edges nearly to each corner so I could see the square border, then gingerly began laying in the pre-creases of a “bird base”. To my absolute delight the paper took sharp creases with NO fatigue. Knowing how the bird base was going to collapse it allowed me to place the necessary pre-creases ONCE, and in the right orientation (mountain or valley).

Once the pre-creasing was done, I then went and liberated 3 of the 4 corners (no turning back now) and collapsed and shaped the Tsuru with no real drama – just being careful of the single remaining attached corner.

White Mulberry Sheet Formation TLDR

| wonko

…so, having liberated 110g (dry weight) of bast fiber from a lovely bunch of Andy’s mulberry tree prunings, it was time to do something with it. I decided to use half (55g), and added it to a plastic container and added a little water to re-hydrate it.

Using the patented “AndyMallet™”, and a recently purchased Ikea bamboo chopping board wrapped in an old pillowcase, I began whacking the re-hydrated pulp using the hardwood edge of the mallet. The shaping of the mallet is perfect, so much mechanical advantage that the fiber was squished in no time.

After about 15 mins of beating, I did a “suspension test”, decided another 5mins was needed and whacked on for another 5ish minutes. BEATING fiber frays the cellulose tubes, allowing complex interlinking of adjacent fibers.

With a tub of “fluffy” beaten fiber, kept in suspension with Okra slime, it was time to try forming some sheets.

My setup was very basic, and after experimenting with the only “vat” like container I had, I abandoned the conventional “pulling” of sheets in favour of the “pour over” method as a means of testing the pulp properties.

1161: Compleat I

| wonko

It is rare that an idea wakes me up – this one did.

I had a scrap of Kraft paper, tore the edges to make it roughly square, quartered it approximately and then began laying in a series of mountain folds starting off fairly close together, gradually getting further apart. I did this on all 4 axes from the centre. I COULD have been much more precise, but I decided to just wing it.

Now, having a series of mountain folds, i used each as the basis of a shallow pleat (by adding a new valley fold near the mountain but decided to do this in an organised way – starting in the middle, I made a pleat, then rotated the paper 90 degrees clockwise then did the next … rinse and repeat until you run out of mountains.

What emerged from the process was a deeply sculptural surface, with a subtle concave 3D structure.

The net effect of the process was also that the whole structure self-locked – ie. it stops itself unravelling by each additional pleat layer locking the previous one in place.

In my head, this then opens up a HUGE new field of exploration – the order in which I form pleats, how far apart they are etc are all delicious variables I must now explore.

This work is reminiscent of the glorious and textural work of @foldsome (Goran Konjevod), and I now completely understand his fascination with it.

I am so interested that even a scrap of kraft (junk paper I use to wrap other paper things) becomes something so luscious to look at – it also WANTS to be touched – some form of paper magic.

1149: NFTs

| wonko

As far as I can tell, NFTs (Non-Fungible Tokens) are dumb:

On this blog, NFTs stand for “Newly Folded Things”, but in the imaginary world of cryptocurrency and blockchain, NFTs were going to be the next big thing.

…until they were linked to money laundering, and people buying them realised that all they were actually buying was an entry in some blockchain register, not the “like, really cool, next level bored ape…man” [I assume that is how “the kids” now speak]

This NFT Bored ape was designed by Viswa Sarathi, and I stumbled across the design leafing through an edition of “Origamiaze – The Indian Origami Magazine Issue 02 December 2022” (yes, I was amazed there was one also)

Folded using duo Ikea Kraft paper, it was a fun (if wildly inaccurately diagrammed) fold – on re-fold I think I would refine the expression to make the ape even more bored.

1142: Daniel Brown’s Seamless Chessboards

| wonko

Having folded Steven Casey’s 8×8 40 grid seamless chessboard and singularly failing to fold Marc Kirschembaum’s 40 grid because of crease-creep inaccuracies, I was approached by Daniel Brown and asked if I was interested in his chessboards – naturally I jumped at the chance. “Seamless” chessboards are deliciously more complicated because it required each square to be represented by an un-broken surface (as opposed to being able to be comprised of bits and pieces of layers – a much easier path):

A "clusterfuck" of seamless chessboards
A “clusterfuck” of seamless chessboards

I say CHESSBOARDS because Daniel has developed a series of coloured/white alternate seamless models of LOTS of sizes, and the skills necessary to migrate edge paper towards the centre to effect colour changes is a thing that needs some work and, often, particular “widgets” (or self-contained localised fold structures).

I started with the 4×4, rather efficiently designed on a 9×9 grid ( 0.444 efficiency). I had a piece of blue-white kami, so gave it a whirl. Even dimensions require different approaches for adjacent corners as they are different colours – the same colour corner exists on the diagonal.

Origami Copyright Theft is BAD, mmmkay?

| wonko

It is exhausting to have to continually deal with a host/domain name server to have unlawful scraped copies of my posts being re-published (with minor, illogical edits) as part of a large but unattributed collection of clickbait masquerading as a content aggregator. openAI24 dot com…

I feel powerless to act as the site has no working “contact us” or grievance process, no one you can email to winge at other than admins upstream of the website.

The best I can do for MY content is to get it blocked at a DNS level, resulting in a “forbidden” message when you try to jump to the actual article. Sadly this does not effect the gallery “preview” of each article. Although it is completely OBVIOUS that all original authors of all content on this site are in the same position, apparently “takedowns” can only be issued by the original author…

It seems the same site is casually ripping off content from Leyla Torres’ ‘Origami Spirit”, Helen Hiebert’s studio and many more. Even though many of us have complained and issued “take down” notices, the site continues to harvest from my site (even though I have now blocked 7 posts at time of this post).

Anyone being similarly ripped off – contact me, the take down process is fairly simple, I am happy to take you through it.

Please feel free to complain to abuse@namecheap.com – they are the host AND name server for this pile of illegal copyright infringement, and the ONLY body actually contactable to do anything about this nightmare

It would be truly humorous if they harvested this post also – they seem indiscriminate THEIVES so who knows, we might be heading for a meta singularity some time soon.

Folding Australia 2024

| wonko

In the perfect storm that was Melbourne, mid-July both 8OSME and Folding Australia happened, one after the other…in the same place.

Folding Australia was a weekend filled with model galleries, folding lessons, special presentations, games (like giant folding and other collaborative challenges), wonderfully talented people and fold-enthusiasts I was privileged to be among.

Joseph Wu’s model display

I had never been to an origami conference prior to this adventure, and therefore had no idea what to expect, I had previously been to loads of educational tech conferences (my now retired teacher speciality), so was open to be surrounded by like-minded people.

Visit to Kami Paper – Melbourne

| wonko

In-between 8OSME and Folding Australia conferences, there was a free-day. Jo and I decided to explore some of the suburban street art, go to Lume patisserie and “accidentally” visit a couple of paper shops.

Kami paper in Melbourne is like nothing I have ever seen – such a variety of papers in the one place, prices pretty reasonable and HUGE sheets (when I buy paper from local Brisbane places like Oxylades, it seems they are selling half-sheets for the same price).

Around the walls were drawers, you are encouraged to open the drawers and feel the paper – it is overwhelming for a paper nerd. I took my time, explored the vast range of different types, origins, fibres and inclusions.

Selecting a range of colours, thicknesses and textures, the shop assistant then pulled the sheets, packed them into a travel-safe post tube that fit in our suitcase – happy days

I ended up with 10 new sheets, all of which I want to fold right now… mostly mulberry, but their range of Lokta, Chiyogami and other luscious papers are sooo tempting. I could spend a LOT in this shop.

Interestingly, they also sell pre-coated Unryushi (it is already crisped up with MC), so very beautiful – I will finally re-attempt Kamiya’s Mantis with a crisp lovely sheet of greey pre-coated Unryu … so excited.

Paper nerds, you must make a pilgrimage here. Alternatively it seems like their shipping is pretty reasonable on large orders, and you can request they ROLL rather than fold prior to shipping – getting un-folded sheets in the post is a rare privilege.

Happy paper nerd.

8OSME – Melbourne, July 2024

| wonko

An unmissable opportunity presented itself where both OSME and Folding Australia conferences were to be hosted in Melbourne, Australia, one following the other. Having never attended an Origami conference (of any flavour) before, I jumped at the chance, but had little idea, really, what was ahead.

Diverse plenary lectures to start the days off

My wife and I got an Air BnB on Collins street for the week. Using the PT> train network, I travelled to and from Swinburne Uni for the international gatherings each day while Jo explored Melbourne Galleries and cafes.

I believed OSME stood for Origami, Science, Mathematics and Engineering – turns out the “E” was for Education, even though in this conference there were 2 Engineering strands … so, ok then. It seems the 8th iteration of this conference reflects origami/folding now so popular as an engineering concept.

1138: The Power of Many

| wonko

I love the geometric world of Tessellations, and have folded many. It is doubly satisfying when you design that tessellation molecule and how it tiles yourself.

This is a hex-point tessellation, and is based on a mathematical algorithm discovered by Aurélien Vermont ( @auregamiiii ) and described in a paper written by them as part of their study in Engineering. The algorithm describes a geometric construction method that lest you raise a n-finned spike from a flat surface and have the surface “heal” around it.

It does so by placing strategic dart pleats that seamlessly absorb the excess paper caused by the spike in a controlled and very flexible way. You can raise a spike at the intersection of a collection of creases (2 or more intersections). The folding gets progressively more fiddly the smaller the spike and the larger the number of intersecting lines.

I chose to derive a hex-spike, that is a 6-crease intersection spike molecule, based on a regular hexagon. Once I had derived all the creases necessary to allow one spike to be raised, I test folded it (just to check – theory and practice are sometimes at odds – some paper designs for origami seem to ignore the thickness of the paper which then breaks the symmetry or distorts the shape) and all was good.

Lang’s “Green Tree Frog”

| wonko

Good paper is such a blessing. I took a long-stored square of olive Vietnamese Dó paper and attempted to fold a “Temple Dragon” – got most of the way through and realised the paper was too small/thick to complete it. Rather than bin the model, I carefully unfolded it, ironed it flat and … the paper had a new life:

Folding paper can damage it – wood-fibre-based paper takes damage (I call it paper fatigue) because the folding process can break the fibres along the crease. SOME paper has strong, flexible fibres that bend but mostly do not break, and Dó paper (made from bark of the Rhamnoneuron balansae tree) is astonishingly resilient.

The colour reminded me of something, as a kid, I used to see all the time – green tree frogs. Naturally I returned to Robert Lang’s “Origami Design Secrets” and re-folded his Green Tree Frog – I no longer had in my stored folds a copy of this lovely model so figured it was time.

1132: Test Fold of a new Baby Tapejara Pterosaur

| wonko

There is so much happening in the world of Origami design, it is amazing to see new models emerging of every subject imaginable. I am working on editing/test-folding a bunch of Chinese diagrams currently, and thought I should fold this beauty to check on the sequence in the diagrams:

I started with 2x 45cm squares of Kraft – intending to fold BOTH the landed and flying versions of this model (yes – 2 different forms in the same model!), reached a part of the diagram I could not get past – I ruined, ragequitted and snowballed one of the sheets in frustration … only to realise the impasse just required a different view of the model.

Plunging on, through a challenging sequence, I muddled to the end and the result is quite amazing. I like that someone has focussed on the “on the ground” version of a model usually depicted in flight with wings extended. These critters were land dwelling, occasionally in the air, and their body morphology is full whack – prolly why they no longer exist (except as remnant critters like bats). Tapejara’s were thought to be particularly agile fliers and formidable predators, remnants of these have been found in Brazil.

This is part of an astonishing collection of new designs coming soon as a book from origami-shop.com and showcases some amazing layer /sheet management. I _almost_ want to go back and now fold the flying version of this model … almost.

Fun, challenging fold. I think folding this critter much smaller represents a huge challenge – the pleats that form the back legs/toes at this size ended up being 4mm – my fat clumsy fingers struggled to fold these accurately (and you form these pleats part way through the sequence – not in pre-creasing). Going smaller will be “interesting” for a more nimble folder.

1130: Villeneuve Ornithopter v1.2

| wonko

When I first read Frank Herbert’s “Dune” series of books, it was the mid 70’s and I was a teenager. The expansive universe captured my imagination like little else.

Dune Part 2 has just been released in cinemas, and the Denis Villeneuve adaptation is visually stunning. On planet Arrakis (Dune), a chosen method of air travel is the “Ornithopter”, described as an insect-like flapping machine.

’Thopters in the current movie series are astonishing, if illogical from an engineering perspective. Variously, ‘Thopters have 2 to 12 wings, each move independently in a coordinated buzz to provide controlled lift and thrust.

The origami world has a few simple ‘thopter designs, most modelled on the 80’s David Lynch film adaptation, so I thought I would have a go at designing one from scratch. Initially I thought to harness an existing base, but decided I wanted 12 wings, in groups of 3, and wanted landing gear, some paper for a fuselage and various flaps for some simple detailing.

There are many design methodologies I could have employed. Circle packing (each circle centre representing the vertex of a stickey outer bit), 22.5 folding to facilitate the point-splitting needed for so many separate flaps, but settled on box pleating.

First I sketched out a rough crease pattern (CP). 12 points along opposite edges of a square. The downside of this arrangement was the points ended up tiny – way too small for the wings. Rearranging them symmetrically allowed me to include extra flaps for landing gear, cockpit and more. Designing the collapse along a 2 unit strip of the central axis also gave me the bulk for the fuselage. I calculated I could achieve this with a 48 grid.
