Tweetris is a lighthearted whole-body interactive exhibit employing a game-within-a-game concept. In the shape-matching game, players compete to make Tetris shapes (tetrominos) with their bodies. Snapshots of players making these shapes are tweeted, then used as tetrominos in a life sized game of Tetris, where players control the placement of tetrominos with their bodies. Tweetris was a collaboration between GEM Lab, HCI researchers at University of Toronto, and digital media artists, researchers and designers at OCAD University. It has been successfully exhibited at public art events, and academic and industry conferences, taking the artist award among 84 exhibits at Nocturne in Halifax, Canada. We used Tweetris as a platform to study the impact of layout, interface, and environmental cues on whole body interaction.  Our paper Tweetris: A Study of Whole Body Interaction at a Public Art Event won the Emma Candy award for best paper at ACM Creativity and Cognition 2013.
