So I want to take a second just to talk about this thing. This is a favorite toy from when I was a kid. I present to you the Yoshimoto Cube (this one is an Entex Brand). Two identical foldable shapes that go from hollow cubes to stellated rhombic dodecahedra that can nest within eachother. It rips! You can just idly fold them in your hands or arrange them in stacks and lines. Intensely satisfying to keep on the shelf and pull down when you want to make some little clacky clacks. Bonus cat pic for scale.
