Poly shape- puzzles are an old friend of mine. Recently I figured out how to cut puzzles on a laser-cutter that became recently availbale near my place. So I'd cut puzzles with tiles made from 6-7-8 squares and 6-7-8 trinangles (full sets of tiles including the ones with holes of course).
I'd made two of the octiamond 6-color wheel (20 cm diameter). I'm willing to sell one, but acrylate is quite expensive. PM me with a reasonable offer. (This one is sold, I'll try to make two or three extra)
from left to right: 66 octiamonds, 24 heptiamonds, 108 heptaminoes, 35 hexominoes, 12 hexiamonds, 369 octaminoes.
- The heptomino circle was made by me in 1987, this solution is by Edo Tmmermans (2005)
- The irregular hexiamond shape has 12402 solutions. I know of no frame with more, please beat me!
- The heptiamond is a solution to the 126/42 problem. First solved by Pieter Torbijn, full analysis by me in 1991 proved there are 55 solutions.
- The octamino frame has three 29x34 rectangles. Unit size i 1 cm, I still don't know where to put it
