Use your Wii controller to create an online whiteboard!
Stefan pointed out a really cool you-tube video the other day. Johnny Chung Lee has used a Wii controller to create a multi-point interactive whiteboard. The hardware is really simple. He’s simply created a couple of pens with LEDs at the tips and switches mounted on the side of the pen. He then simply points the Wii controller at a screen where a projector is displaying his PC desktop. The Wii controller connects to the PC using Bluetooth. Johnny has written some code on the PC to tie it all together, and the result is astonishing!
