Hideaki Azuma pointed out quite a few updates to his original leaf fold design, mentioned here a few weeks back.

On his further explorations of this concept, he runs through a large number of variations on paper size, shape, fold angles, folding patterns, and more. Some of them are really just fascinating structures.

This one reminds me of Melisande’s variant of his original leaf fold.

He progresses through a number of diffferent leaf shapes, and then starts going into some heavily twisted topology, like these ones (my favorites):

These twisted shapes remind me a lot of Philip Chapman-Bell‘s (aka Oschene) 3d boxes and jars- I love the way all these things just spring up out of a flat sheet of paper.

Much interesting and fertile ideas here. Thank you, Azuma-san!
