Here is my build of the possible upcoming Cheapass game Tak. http://www.cheapass.com/games/tak
The pieces are built to the rough specs included the the rules, and colored with fabric dyes.
I was a little skeptical that the asymmetric pieces would work well when laid flat, as I am a little OCD, but it was't an issue at all on the first few play throughs.
Now I just need to figure out how to create a board that is useable as 4x4, 5x5 and 6x6
