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.
Looking at my “must fold when time” pile, I remembered a diagram destoned for a Peter Buchan-Symons “Folding Fantasy” book:
This lovely duo colour dragon is designed by Matthew Dunstan, and is an interesting variation of a classic birdbase with some grafts for the head.
An intense little fold in places (the head in particular is really fiddly and thick), I really like this little western dragon with good proportions and a unique character.
I folded this from a 35cm square of Duo Kraft paper – a mistake in retrospect, it would have been easier (less finger bruising) with a larger thinner sheet. Originally I planned to fold it with my Shadow Thai, but I think it is too thick … now I know how the fold works I may still give that a go.
EDIT:
Folded with a 40cm square of origami-shop Duo Thai paper, with some extra detail and shaping, this little beauty is a treasure indeed
Browsing through the latest JOAS Tanteidan Magazine, as one does, I came across a seemingly simple but delicious little pentagon box in the shape of an acorn designed by Tomoya Kariya:
Exploring the sequence, I figured I could shepherd some of my hand-made paper through it, and reasoned that banana paper would make a beautiful cap, lemongrass and cotton paper would contrast nicely for the kernel.
I turned to my stash and discovered I had some smaller offcuts, so set about making matching 6″ squares of the rough but beautiful paper.
Folding hand-made botanical fiber paper is really hard on the finger tips – the lemongrass paper is actively spikey, but, being strategic and deliberate when manipulating tough fibers that lay on creases, I was able to coax the paper to take shape.
I LOVE the result – the handmade paper is PERFECT for this fold, it enhances the organic shape and makes it feel like a precious relic.
Schrödinger’s Cat, as a thought experiment, states that if you seal a cat in a box with something that can eventually kill it, you won’t know if the cat is alive or dead until you open the box. So, until you open the box and observe the cat, the cat is simultaneously dead and alive.
We often use Schrödinger’s thought experiment to explain the concept of superposition. The experiment states that a hypothetical cat is locked in a box with some radioactive substance controlling a vial of poison. When the substance decays, it triggers a Geiger counter that causes the poison to be released, thereby killing the cat.
Since the box is locked, and we on the outside don’t know whether or not the radioactive substance has decayed and released the poison, we can’t tell if the cat is dead or alive. So, until we open the box to know for sure, the cat is both dead and alive. Mathematically speaking, there’s a 50 percent chance the cat is dead and a 50 percent chance the cat is alive. Source.
This is Sebastien Limet’s Shrodinger Square, a delicious exercise in folding a figure then hiding it inside another structure. I folded this in baking paper, and it is a little too transparent I think (I tried it in printer paper and it was too thick and opaque).
I like that the cat is made of the body and tail at opposite ends of the 5:1 sheet, closing and locking it brings the two pieces together in silhouette. Clever.
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.
Cruising the channels on Origami Dan, I found a CP for a fold challenge I had missed, but decided to give it a whirl anyways:
Designed by Scott Okamura, this seemingly impossible fold featured a traditional Tsuru (crane) folded in the middle of a large page of duo paper – the surrounding paper is then formed into a box.
As lightning crackled from the raging thunderstorm above, the electrodes sizzled, the smell of burning flesh hung damply in the air as the creature stirred on the table, accompanied by a mad cackling laugh interspersed with hysterical cries of “It’s Alive!!!”:
Apologies to Frankenstein lovers, but let us face it, this model is a bit of a Frankenstein. It is the result of putting a Satoshi Kamiya RyuJin 2.1 dragon head on a classic Tsuru (Crane)’s body. Nuts – right?
I first saw the CP (Crease pattern) for this on one of the Origami Discord servers I frequent (RyuCentral), and thought … how odd, how hard could that be??? Stupid man!
Dividing the paper into quarters and half along one diagonal, I reserved 1/4 on the diagonal for the crane and then set about laying in the graft CP for the dragon head in the remaining 3/4. It needed a 23 division grid that intersected at the square opposite the crane. Accuracy was the key. Grid laid in, I then started setting the pre-creases necessary for the head – stupid man, fucked the first set up twice (because I did not count), finally, pre-creasing done the collapse began.
I have folded many Ryu Jins, many versions, many times, so it was like returning to an old friend, interestingly muscle memory helped me not find the horrendously complex manipulations difficult at all (or maybe my subconscious was blocking the trauma) but to my surprise the accuracy I obsessed over early on paid off later allowing a pretty tidy collapse and NO damage to the reserved 1/4.
With the head collapses through early base, late base and shaping, I isolated and shaped the little arms and then set about working out how to fold a crane with the head as the head. Annoyingly I chose the wrong orientation first (der) and the head was upside down and backward. Just when I thought I would have to perform an infamous “neck twist” (interestingly NECESSARY on full RyuJins), I tried unfolding the crane and reversing all the creases (ie. folding it inside out) – to my delight that solved the problem (and THEN I remembered CPs are usually drawn WHITE SIDE UP – what a dickhead!!!).
Colour-change models are astonishing to me, designing models that use colour change are something special:
I have folded a number of different models like this, nothing quite like it however – what sets this model apart form any other is that each “tile” on the board is a seamless square.
Folding this from a SINGLE UNCUT square ends up being a bit of a brain-fuck. The paper was blue one side, white the other (actually cheap and nasty 70cm wrapping paper from my local dollar store). Distributing the “colour” is achieved, mostly, by bringing the sheet edges up through pleat bundles using a variety of techniques.
You can see the final location of the 4 corners of the original sheet in this development photo:
Planning/designing of a model like this is beyond me – pre-preparing the colour changes means that every bit of the paper has a job – either visible “tile”, spacer, flipper, mover etc to get the bits of colour to get where they need to go. Fold accuracy is the make or break of such designs – novices who use a “near enough is good enough” approach will not succeed here.
I was asked to test fold this, by Steven Casey, prior to publication. The diagrammed sequence is intense, starting with a 40×40 grid. Most of the folding is working on the wrong side, creating interacting pleat stacks that sit flat but that strategically manipulation pleat order. The run towards the “checkerboard” effect happens around the edges first, they they are migrated further towards the centre (although really only in a 4-unit strip around the periphery.
1: Knock knock. 2: Who's there? 1: Amos 2: Amos who? 1: A Mosquito. <insert hysterical laughter of a little kid (me) amused by the first dad joke he can remember his dad telling him> True story.
I have bought many sheets of the most amazing paper, all dutifully stored in my “cave”. Over 10 years ago, I purchased a full sheet of black Unryushi single tissue because I HAD to have it, but having NO plan to use it.
Unryushi tissue is beautiful, painfully thin (24GSM) but gloriously adorned with visible mulberry fibres. It comes being about the stiffness of facial tissue – I misted a large window with water, rolled the sheet onto the wet glass (shiny side down) and then added a coat of MC (Methyl Cellulose) to the back side, removing air bubbles from the centre out.
Even wet, the Unryu is really strong, but to make it foldable I needed to crisp it up. I managed to cut a 60cm square, leaving a >12inch selvage for another project.
The latest Tanteidan magazine had a enthralling Mosquito design by Yoshio Tsuda and I knew I NEEDED to try it, but lots of the model is 12+ layers thick, I knew I needed some crazy thin paper … hence the Unryu. I decided to fold Version 1 of the Mozzie, knowing that Yoshio also published a crease pattern for his revised design – that will do for another day.
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.
Perusing origami books, as you do, I chanced upon a delightful little pelican:
Designed by @tommy03, making use of a beige/white duo 6″ kami square, this delightful model captures the essence of a pelican better than any other I have seen.
“What a wonderful bird is a Pelican – whose beak can hold more than it’s belly can.” – A rhyme my mum used to say to me as a little tacker – hoping to gift this to another mother tomorrow.
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.
A long while ago, a new artist on the scene, Fynn Jackson, started releasing astonishing mask crease patterns on social media.
He later commercially released his designs and I purchased his crease pattern packs for masks 1-35, along with the more recently released noses 1-9.
I love Fynn’s work, and eventually will develop my own CPs of faces. There is so much expression in the score and fold bundle, so decided to expand my collection and try out a bundle of manilla card in the process. I contacted @Jacksonorigami and asked him about selling finished masks – he (to my surprise and delight) freely encourages folders to monetise their rendering of his designs, so long as we do not share the purchased CPs (so please DO NOT ASK) …. so I got to thinking about an upcoming Gallery shoppe associated with my papermaker friends PAQ – put 1 and 1 together and arrived at 6.
I set about folding 6 faces I had not tried before from Fynn’s rich collection of characters, each using different aspect ratios, techniques and all quite wonderful. I was encouraged (by some of the wonderful ladies in PAQ – I am looking at you Ann and Wendy!) to consider selling, and began thinking about displays that would make them work as purchaseables.
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.
On Sunday during the weekend the PAQ “All Stitched Up” exhibition opened in Gympie Regional Gallery a fortunate group of paper makers were able to spend the day at Dion Channer’s paper mill. Michelle, Vanessa, Wendy, Sue, Heather, Ann, Joolie, Marjorie and me, Peter were in for a treat with Dion and his partner Sue Purnell. Surrounded by the bush, among music rooms and yurts, pavilions and lakes, Dion’s mill was a large shed with a bespoke collection of gear and infused with the passion of a master papermaker.
Over a morning cup of tea, PAQ members talked with Dion about individual goals and hopes for process assistance, we learned about the available fibres and equipment we would learn to use during the day. Following a tour of his eclectic property, we retired to the mill and began with an orientation.
