This is probably a long shot, since this is so old, but I was looking for a tool to play around with some ideas for a hexagonal chess variant and I stumbled on this simple little beauty. everything else i've found is ... well, not really great.
I'm not a coder. I'd really like to be able to cycle through 4 colors, so i can make a traditional 3 color chess board, and highlight the units that a peice may move to.
