912: (362/365) Abandon Ship!

As the year 2017 swiftly comes to an end, after seemingly being in a hurry to do so all year, it is almost time to abandon ship:

Time for one last waltz, one more visit to the buffet, perhaps a cigar on the poop deck then it is lifejackets on and over the side into the icy uncertainty of the new year. 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

749: (199/365) Oyster Box

David Mitchell is a legendary origami designer, responsible for countless geometric wrangles:

This is an “Oyster Box” – a box that resembles a bivalve, that locks together rather satisfyingly and opens to reveal a spacious interior. Continue reading

631: (81/365) Four Cubes

Sometimes a modular is deceptively complex, this 6-part modular from David Mitchell is no exception:

Four cubes, interwoven in evil ways has done my head in for days now, I simply could not (1) imagine the shape it was going to end up; and (2) make the modules connect in ways that made sense. Continue reading

629: (79/365) Artefact

I quite enjoy folding modulars – the way they combine to make a larger form can be fascinating and this module is no exception:

This is Dave Mitchell’s “Artefact” module, it can be put together in 2’s and 6’s. Continue reading

627: (77/365) Collapsible Cube

Toys for people with ADHD are all the rage – people pay for things with switches, moving clicky bits and spinney things because, reasons:

This paper toy continues to be an enigma. Made of 4 modules, it is a twisty cube that also folds flat in a myriad of ways that break your brain. Continue reading

613: (63/365) David Mitchell’s “Gemini”

We are heading into assignment season in many of my classes – this means my students are busy getting on with it, occasionally asking for help, but I am stuck there inert and when I get bored I get naughty:

…so I fold stuff to keep me awake. Modulars have an advantage that, once you have mastered the module, it is largely “rinse and repeat” until the final assembly. Continue reading

459: Electra

Browsing an amazing book by David Mitchell called “Paper Crystals”, I spotted an interesting modular ball based on pentagons tiled with triangles named Electra.

Coupled with the original model was a suggestion that it was possible to make a 60 module version consisting of pentagons surrounded by squares separated by triangles. Continue reading
