Some members over at Crochetville are doing a Tetris inspired afghan CAL. (http://www.crochetville.org/forum/showthread.php?t=45794&highlight=tetris)
I decided that this one I had to join in on. Most people are doing 4" granny squares, but I decided to just make a sc graph-ghan instead. I made the graph (3 times) and have started to crochet it. My family actually likes this one too......surprise, surprise, surprise. We were always big Tetris and Dr. Mario junkies. Spent many hours playing those games!
