“A central problem of geometry is the tiling of space ... However, many tilings in nature are characterized by shapes with curved edges, non-flat faces, and few, if any, sharp corners.

Shapes with flat, angled sides, like pyramids, work best to create 3D shadows. Once you've made your selections, take your flattened cardboard box and start tracing triangles (or the shape of your ...
