Tweetris
Tweetris 
Described as a combination of Tetris, yoga and Twitter, Tweetris is a Kinect-based two player game based on whole-body interaction. Tweetris is an art project resulting from a common effort of researchers at Digital Futures Initiative, OCAD University, computer scientists at the Dynamic Graphics Project lab, University of Toronto and independent artists.
The core part of Tweetris is the shape-matching game, where two players race to match the shape of their body to a tetromino, i.e. a shape composed out of four squares taken from the game Tetris. This gameplay idea was inspired by the Japanese television show Brain Wall. Whoever makes the correct shape fastest has their picture taken and uploaded to an account on Twitter (@TweetrisTO, @TweetrisTEI). Anyone can go to a website and play a custom game of Tetris, where the pieces are overlaid with images of winners from the shapematching game
