Yet another twist on a classic video game, Twetris replaces the iconic coloured blocks of Tetris with tweets grabbed from Twitter. The game is still played the same way, you muse use your arrow keys to move and alter the position of the pieces as they fall in order to build formations that complete a solid line of a single colour. The real challenge is trying to read the Tweets while you find a place for them. Twetris is an excellent reminder that everything, yes everything, you write on Twitter is for public consumption and might even end up as a game piece or component of someone else's website.
