M.C. Escher Square Tessellation Ornaments

Imatfaal's awesome post on Escher's tessellations on Polyhedra reminded me of some ornaments I made this summer.  I made some of Escher's square tessellations onto cubes and then reprojected them onto spheres.  I actually used a 60 sided Deltoidal hexecontahedron since that net is fairly easy to fold and looks pretty round.
