This is pretty cool. I was actually able to follow the instructions and make something that worked on the first try. I used 4-inch squares of paper and 2-inch packing tape, just about right.
It’s not clear from the video, but you end up with 6 tetrahedrons joined edge to edge in a circle, sort of an angular torus that turns inside out. The faces of the tetrahedrons are colored so you see 6 same-colored faces at the same time, and the color changes as you turn the torus inside out.
