mikejuk writes with a light piece in I Programmer about a neat Kinect and gigantic projector hack. From the article: "If you remember Breakout — rows of blocks a the top of the screen and a paddle to bounce a ball into them to destroy a block — then you might not feel nostalgic about it. After all, it was a very limited sort of game. However, take one Kinect and one building and you have something quite different when you use it to create a Breakout game. The bricks, ball and paddle all projected onto an old building and the player moves from side-to-side to control the paddle. The player's position is being detected by a Kinect, is there no end to the fun you can have with this gadget. The really clever bit, and you might not notice it unless you look closely at the video, is that the ball bounces off real architectural features of the building — like the windows, for example."
