I was shown these Johnny Lee youtube videos of his remarkably cool wiimote hacks and I feel an urge to make sure you lot don’t miss out these gems:

Head Tracking for Desktop VR Displays using the WiiRemote

and

Low-Cost Multi-touch Whiteboard using the Wiimote

They really make me want one of these to play with. Unfortunately, all the software Johnny’s done for this that is available on his site seems to be C# for Windows! ;-(
