I did this about a month ago when i first saw his video's and it worked quite well

The sucky part is having to get a proper bluetooth adapter
Here is a list of supported adapters
http://wiibrew.org/index.php?title=List_of_Working_Bluetooth_DevicesI use a homemade projector and just stuck a IR led on the end of a pen and used his whiteboard software it worked out great and my nephew loved drawing in MS paint on the wall it was cool i tried to use it in quake 3 arena to see how it would feel like in his 3d video but the whiteboard software didn't work

it did shoot but wouldnt move around
I havent played with it for awhile cause for some reason glovepie wont work on my pc so i can't try it with quake i was thinking how it would look to use some of the LCD glasses and have the IR leds on the side and see how much of a VR experience it felt
