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.

1128: Origami Computer

| wonko

For a system to be considered “Turing Complete”, it must be able to be used for completing any computational problem. In the world of DIGITAL Turing Complete setups, these computations are achieved using simpler binary operations (like NOT, AND, OR, NOR, etc.).

In a paper recently released by Mathematicians Thomas C. Hull and Inna Zakharevich, they propose flat-foldable crease patterns for origami “processors” that simulate a number of simple binary operations (namely NAND, NOR, AND, OR, NOT and a few ancillary operations) making the theoretical proposition that flat foldable origami is Turing Complete.

I folded a few of the paper’s logic gates, and made a video of how they work – have a look:

Although this is a little nerdy, I can at least conceptualise the idea that a network of interconnected origami processors could, theoretically, actually do something useful. Technical challenges exist with having such crease patterns co-exist on the same sheet, in sufficient quantities to represent anything other than single bits (0/1 or On/Off or True/False), but the idea is none the less tantalising.

I link to a copy of the paper here: FLAT ORIGAMI IS TURING COMPLETE

1121: Santa/Satan

| wonko

Comes the time of year when we tell little kids that a morbidly obese stranger in a red suit breaks into their house (by coming down a chimney or other entry point if there is no chimney), eats some random snack, feeds a portion of that snack to a reindeer (who has a birthmark on it’s nose) and then leaves presents, regardless of whether you have been an entitled little shit all year, or a saint:

As a parent I was complicit in this lie until my kids (fairly early on) cottoned on to the fact that this whole thing was so very unlikely, and merely a mechanism for justifying a mound of presents under the xmas tree.

I wanted to try out the new paper pack of Satogami I got from Origami-shop and this festive fold seemed like the perfect opportunity given the latest Tanteidan magazine (which contains it’s diagrams) arrived this week also.

Duo Satogami is quite thick. I bought a paper pack of 58cm squares, mixed colours and love the vibrancy of the red/white, and also love the texture of the paper. I _want_ to report that pre-creasing Satogami was easy … but … I really struggled to my the reference folds and to fold accurately because of the thickness and texture. The paper reverses fairly poorly also (meaning I had to correct lots of folds for accuracy as I went to ensure alignment of layers and edges during more complex moves.

1116: Alas….Homo Papyrus

| wonko

Things have been busy, lots happening in the real world so it is sometimes nice to get lost in a fold or two:

This lovely fully 3D skull, designed by Naito Yukata and wrangled from a 3:1 rectangle has been quite a journey.

The pre-creasing was fiddly but laid in landmarks that then aided the staged collapse. I found it easier to collapse parts of the model separately, then open the sheet back out to do the next section, laying in the final resting creases as I went – this meant that the “all at once collapse of the top part of the skull was easier.

The teeth introduced a lovely layered pleat structure I had not seen before and the overall shaping is a bit of an art I think.

Double-Star Flexi-Cube

| wonko

There are many models I just HAVE to have in my folio – David Brill’s “Double-Star Flexi-Cube” is one such model:

I first folded this back in my first 365 origami project (the original reason for this blog). At the end of the first 365 I held a charity auction and the original white DSFC provided a rather nice amount for my nominated charities.

I have only just got around to folding it again. This model requires A-series paper proportion, so I decided (insanely) to use A7 sheets, and chose 2 bold colours (red – yes that is RED, my phone camera seems singularly unable to photograph it, and purple) because I had 4 sheets of each. Each A4 sheet is cut into eighths – 64 sheets (32 for each cube)

deliciously, you fold 2 identical stars then, by the magic that is geometric topology and strategically placed “hinges” you can morph a star into it’s own negative (a cube with a star-shaped hole) then nest them inside each other.

I love this to bits, but must admit to having (again) to cheat on this model – the “locks” are not very positive, it tries to pull itself apart and there is little locking it together (bar some overlapping edges, simple flap tabs into pockets etc) – this is a bit of a pity. I used small strategically placed glue spots to stop it exploding every time I even looked at it suddenly.

Flexi-geometry is remarkably satisfying to play with, the geometry of this cluster is delicious.

1107: WALL-E

| wonko

Although (technically) a re-fold, the last time I attempted to fold this I had a partial crease pattern and a broken incomplete set of instructions in Russian, and just muddled along. I am not sure the resultant model even looked like Wall-E, but I was happy to sort of nut out a scheme for making his tracks.

I stumbled across a set of partial diagrams by “Tosummerny” in Chinese that seemed to surface more of the actual process, so decided I had to have another go.

I went big – 90cm square – seems excessive …but … I have another exhibition pending and thought this might make a good display piece if it ended up tidy enough.

The diagrams clarify the construction of the pleats necessary to form the main body, and how they cleanly articulate to make the beautifully treaded tracks, and also simplified what I had in my previous attempt mangled together to form the eyes.
