We were inspired by a post on Twitter by Olivier Longuet shown below. The object in the photo is an icosahedron, a 20-sided 3D shape, made out of three golden rectangles with side lengths that obey the golden ratio (1:1.618033…). To make a cardboard version of the icosahedron, print out this document and follow the instructions! You can also make
