So, at one point during the latest MathsJam Annual Gathering the topic of origami Soma cubes popped up. I had folded one using sonobe modules a while ago, but decided to try my hand once more. So, please welcome my new rickety origami companion.
John Horton Conway has died.
Sigh.
One of the most unique mathematicians and human beings who ever lived.
Five years ago he was game for this April Fool's prank

August 24 marked the 120th birthday of Argentinian author Jorge Luis Borges (1899-1986), whose works were often steeped in the flavour of mathematics.

Now, in a real-world scenario the "this can be done indefinitely" bit in the Shout was probably a bit far fetched. In the video I folded my HHF just 3 times, but I can assure you that it should last longer than your average Italian government.
So, I hear some of the hexahedroflexes were less than (com)pliant. It can happen, and in general it takes some persuasion for things to work well. Here is a video showing how to properly flex one. You might also want to pinch each fold a little to make the structure more docile.
The idea is to push all the six tips towards the centre. And to press the "sides" of the HHF back in place, should they "pop out" during the "flexing".
@timarumathsjam Glad you guys had a good time! We are meeting next Tuesday, so right now I can only hope our Shout meets the same warmth here as well. 😅
