Today we printed a large copy of a Rhombic Tricontahedron (Day 203) to give to a doctor friend who is leading the pack of those trying to figure out a vision problem of mine. It is so great to have a doctor that is actually curious about solving a puzzle; so many others send me on my way if they don't see an immediate answer. One puzzle he's interested in is George Hart's Frabjous assembly, which is based on the Great Rhombic Tricontahedron, which itself is based on the Rhombic Tricontahedron we printed today (which while "large" is not "great").
