890: (340/365) Arches Tessellation

David Huffman is a bit of an origami enigma it seems – he pioneered a bunch of tessellations and surface corrugations and seems to be one of the first to explore curved creases and their bizarre effects on flat sheets:

This is is “Arches” tessellation, an intriguing offset brick valley folded grid that then has parabolic mountain folds at each intersection. The resultant sheet is really hard to tidily collapse (in my experience) – perhaps it was the paper or the scoring technique I used to form the parabolas, or perhaps it was the parabola itself – with no guidelines I just sort of guessed a curve.

You get a sort of waterbomb base forcing one trough deep into the arch of an adjacent fold – when it is tidied up it is fascinating – I could see uses for this as an interesting textural pattern or ambient light panel as it makes funky patterns when backlit. Continue reading

888: (338/365) Cubo Twist

This charming 6-piece modular cube is designed by Francesco Mancini and is included in his booklet “Mancinerie”, which I think I purchased from the BOS shop online:

Each face is a twisted square. Folded from A5 sheets, the pre-creasing is pretty easy and the twist is satisfying. Continue reading

886: (336/365) Second-Level Octospiral

Paper fractals are fascinating self-repeating/reducing designs that are relatively new in the origami world:

This 2nd-level “Octospiral” is a model I saw in one of my last BOS journals before my membership lapsed. Designed and modified by Roman Diaz, Endre Somos and Meenakshi Mukerji, it is a delightfully dense spiral that, theoretically, could keep reducing inside itself indefinitely. Continue reading

885: (335/365) Trefoil Knot

In topology, a branch of mathematics, the trefoil knot is the simplest example of a nontrivial knot:

This is Kevin Hutson’s design, well CP really, that I sort of just nutted out after mis-folding it 4 times and uttering some bad words (sorry Mum). The observant amongst you will notice that it starts and finishes at the same point – like a mobiius strip on acid. Continue reading

883: (333/365) Cake Tin Liners

…then my wife casually asked if I could line some cake tins:

A simple fold, unequalled as a way of protecting a fruit cake from extended baking – the outer layer is 35cm square kraft paper, inner is 25cm greaseproof paper, they fit snugly in the tins. Later they will protect the maturing cake as it regularly bathes in rum. Continue reading

870: (320/365) Nymph Ball

Exam invigilation is one of the most boring things that exists, when possible I fold repetitive things during them (thus allowing me to be vigilant and productive):

This is a 30-piece modular ball made from Ekaterina Lakasheva’s “Nymph” module – simple tab and pocket creations folded from 7.5cm squares. Continue reading

864: (314/365) 6-part Rhombicuboctahedron

…yes, I know, a day late but, meh! Always on the look out for fascinating geometry, I had put this 6-part Rhombicuboctahedron, designed by David Mitchell, in my “fold this when you get a moment” pile:

6 relatively simple modules interlock to make a fascinating ball-like structure but the devil is in the details. Continue reading

863: (313/365) Casa Blanca

I always find it remarkable that with relatively few folds, we can hint at a shape so familiar that our minds go nuts and full in the visual context:

This is Roman Diaz’s “Casa Illusione”, a faux 3D dwelling that nicely plays with light, angle, perspective and proportion.

I chose to fold it white (Casa Blanca) with a terracotta roof, and imagine it perched on some Tuscan hillside, awaiting my return after a hard day wining and dining at some cantina.

861: (311/365) Tessellated Star Box

I saw a photo sequence of a tessellation that was fashioned into a box and knew I had to try it:

Well, I say tessellation, but really this is just one molecule, but it is none the less beautiful. Continue reading

844: (294/365) Our House, is a very very very fine house …

It seems to be the season for buying houses. A couple of my work colleagues have, individually, in the last little while purchased houses:

The “Great Australian Dream” apparently is to own your own home – this seems irrefutable proof that it is still entirely possible. Continue reading

843: (293/365) Origami Architecture

I was doodling with a 17cm square, divided into an 8×8 grid and collapsed, via a photodiagram (and a bit of wrestle-magic) into a curious but possibly useful surface corrugation/tessellation:

With an exercise in patience, fold accuracy and layer management, a “swastika”-like collapse becomes a sunken 4 segment recess, then the edges tidy up with some propagatible pleats, making this tesselatable. Continue reading

841: (291/365) Shuriken

Now I am pretty sure that “ninja stars” were not really a thing, but – meh:

This rather charming woven six-pointed star is an interesting exercise in re-working a square into a windmill-like hexagonal base. Continue reading

833: (283/365) Porous

It is interesting how things sometimes just work themselves out:

Here was me, panicking because I had nothing ready or in mind for today’s fold, came home and the latest Tanteidan Magazine was in my mailbox. Continue reading

832: (282/365) “Love You Longtime”

Apparently there is an Origami Olympiad – an annual internet competition where folders are pitted against a collection of challenging folds for points:

This model is the first one from the IVth International Origami Internet Olympiad, a publication that contains other things I will try also. Continue reading
