For a little while I was on some kind of creative "kick" and I came up with this crazy thing - a Tetris poster. The back is your standard black posterboard cut to 10" wide by 20" high (the regulation size of a Tetris well). Each block is approximately 1" square, but they're not perfect. It wasn't until late in the game that I got a craft punch that made it easier to cut 1" square blocks. All of the blocks were cut from cardboard packaging - cereal boxes, frozen food boxes, etc. Any time I saw an interesting color or pattern, I cut blocks from it. The shapes are all in Tetris regulation colors. Enjoy.
