Here is a website that has some cool DIY stuff for the Wiimote. It shows you how to connect the Wiimote up to the PC with bluetooth and then turn your pc/laptop into a touchscreen. You can also create a whiteboard by connecting up a projector, but most important, Johnny Lee shows you how you can have a full 3D experience when playing a FPS game. Totally cool!!
This is pretty cool. This laptop uses touchscreen holographic technology for its display (or the closest thing we have to it). The screen is totally transparent until power is turned on.
