Bubblegym is, as far as I know, the very first computer game that reacts to how the machine is tilted. Many Apple laptops have a chip on the logic board that is there to signal if the computer is dropped. Thanks to Amit Singh (kernelthread.com) and Christian Klein, this chip's values can be read and utilized for your amusement. The gameplay is simple but challenging, control the balls by leaning the computer and get to the fruits before they disappear.

What’s new in version 1.1
Updated on Sep 07 2011
Version 1.1:
Finally updated after almost 4 years! Updated default behavior for many new models. Modern computers have become so fast that the game became unplayable on them. This updates aims to fix that. Please send a feedback email if the game is too slow or fast on your machine or if the tilting feels backward. Please include which machine you've got.
I think this game is a great promise, but appears to be unfinished. The graphics look cruel to the eye and this is the stingiest demo I have ever seen, as it runs for ~5 seconds.
There is some fun though listening to the Handel music afterwards ;)
1) improve the graphics
2) add mouse/keyboard support for the rest of us
3) port it to cocoa maybe
And see if Apple will bundle the game with the PowerBooks!
Very cool.
