Following up on my fetish for getting my Thinkpad's motion sensor to do, I checked out a clever hack that turns the sensor into a motion controller and makes games respond when you tilt the laptop. Just like the Wii's motion-sensor controller, but way more expensive.
An introduction to the process, and relevant links, are on the Lenovo "Inside the Box" blog.
I followed the instructions and was quickly playing Tux Racer, a game where you guide a belly-sliding penguin down a snowy slalom course. The Thinkpad's tilt sensors are responsive, and the game is fun, but this ain't no Wii. Using my 6-pound T60 as a game controller got tiring fast. Still, it's a great show-off app.
