This uses rigid rods. Seems obvious in hindsight?

This is what I was trying to do originally, I wonder what it would look like if I used rigid rods for the edges.

I haven't raytraced anything since last October.. and I've been meaning to take POV-Ray for a spin at last. Then came @curved_ruler's recent posts about Li Dequan's strange attractor, and I knew exactly where to begin :) #MathArt

I tried to model these origami as transformation between cube and octahedron in Geogebra, but ended up with this instead

Happy birthday to #mathematician Felix Klein (1849-1925). This is a hand-carved and hand-printed image of the famous mathematical object, the Klein bottle, printed in a gradient of pale yellow-green to darker blue-green on paper 8” by 8” (20.3 cm by 20.3 cm). First described by mathematician Felix Klein in 1882, this object has a single surface, rather like a 3D version of a Möbius strip.

Two modular origami cubes made from 1:√2 rectangles and squares (Canoe Unit 90° by me).

Three modular origami octahedra made from three different kinds of rectangles (Canoe Unit 60° by me).
From left to right, the rectangles are 1:√2, square and 2:√3.

Yes I carved a maze out of a Pinwheel Tiling!

@mrdk @unnick I'm kind of surprised and not surprised about how the tetrahedron turned out.

@mrdk @unnick And here’s the rhombic triacontahedron for the dodecahedron/icosahedron (again without scaling the bars to have constant length).

@mrdk @unnick This version shows how the cube/octahedron works using a rhombic dodecahedron (without scaling the bars to have constant length).

I'm not sure that these are related to the Jitterbug transformation.
This is my recreation of unnick's original cube/octahedron loop. I used the rhombic dodecahedron and rhombic triacontahedron for this and the previous loop. They remind me of tensegrity structures.
BTW, I made a couple of origami versions of the Jitterbug transformation many years ago. This one https://foldworks.net/wp-content/uploads/2018/06/jitterbug.pdf works better than the first version https://britishorigami.org/academic/davidpetty/origamiemporium/lam_jitterbug.htm

I couldn’t resist making this in Geogebra: morphing between a regular icosahedron and a regular dodecahedron.

My piece Spaceship Earth.
Thinking about the only home we will ever know on this Earth Day.
