My husband, Mike, loves origami. We’ve been together for about five years and I remember way back in the day (those crazy college days) that he enjoyed an occasional crane or pyramid made from a dollar bill or fancy paper. In the last six months he’s gotten into the art again. Tonight as we relax he has been working on a cube made from smaller cubes created out of business cards. He found this website that gives instructions on all sorts of neat modular origami pieces. He is working on the very first project. The Menger Sponge. Here is the final product. So cool!
