Stained Glass Tangrams

The classic Tangrams puzzle game using stained glass tans. Backdrops are historic Chinese art from as far back as the 17th century. I was inspired to use them because Tangrams originate in China. However, most of the artwork actually predates Tangrams puzzles, which didnt appear until the early 19th century. Complete source code for this game is available on Github.
