This is making the rounds of various places on the internet, but is an amazing video of a touch screen built using a Wiimote and a simple IR LED in a pen: http://www.cs.cmu.edu/~johnny/projects/wii/
There must be dozens of possible HA applications for this ... sure it isn't finger based and you need a stylus, but on the other hand it is multi-touch, so you could build a cheap Microsoft Surface knock-off.
Mounting one on a cheap 22" LCD would give a large in-wall touchscreen at a fraction of the price of a commercial offering.
Anyone else see a good excuse to build one of these?
