With Linux installed, and the right drivers, the Wiimote can be used as a [gyroscopic] mouse on the PS3.

In unrelated news, I was lookingat Gyroscopic mice the other day.

And the word "seamless" springs to mind when I say I'm using the PS2 eye-toy as a webcam on my PC, and it's better quality than any other webcam I've seen.
