Stellated Icosahedron (Paolo Bascetta)
As to be expected at an origami convention in December, lots of people folded Paolo Bascetta's stellated dodecahedron, commonly known as the "Bascetta Star". I decided to give it a go, too, and here's the result. I used 30 squares of foil-paper-foil sandwich, which isn't the easiest to work with. That's why I only use it with very simple models, and the units are straightforward enough to fold.
