Decorative cube

For fans of the genre, here is a modular origami: a cube designed by Lewis Simon. It is made of 12 identical units folded from square sheets. As is often the case with this kind of origami, the unit itself is easy to fold; you just need a little patience to fold all 12 units and then to assemble them. As you can see, both sides of the paper show, so the cube will look nicer in two-colour paper. I have made some with 15 cm squares, and others with 7.5 cm squares.
