These arrived a while back, as you can tell from the dye colors. These are parts for my game Tess, the Tess Polygon Module and Tess Disc Module. This is a chess-like game played on tessellations of hexagons, squares and triangles. The pieces are distinguished by which polygons they can occupy. The polygons interlock, and are held together by mutual tension (3 to 6 at a vertex). I used "carriers" to keep all the parts together, a combination of cages and interpenetrating "sprues". This last image is a double set, stored in a portable Stanley organizer with removable compartments. The current Polygon Module has 10% more polygons than shown, but would still fit.
