How does the Yoshimoto Cube work?

The cube is made up of eight interconnected cubes which can be folded or unfolded indefinitely. The unfolded cube can be dissected and reassembled into two stellated rhombic dodecahedra, each of which comprise half the volume of the original cube, making it a kind of three-dimensional dissection puzzle.

How do you make an infinity cube out of paper?

Step 1: Fold one piece of paper in half to get the halfway fold mark. Step 2: Open up the square and fold each side edge to the crease line you created in step 1. Step 3: Fold the smallest edges over to create a halfway crease going the other way. Step 4: Repeat five more times using different colors.
