Rear Projection TV as a Giant Touch Wall

If you've been salivating over the big flat screen TVs and trying to figure out what to do with huge rear-projection TV you bought in the 90's, I have an answer for you: Turn that old rear-projection TV into a giant touch screen!

MAKE magazine pointed me to this blog post on IDEO Labs about how the converted a 67" rear-projection TV into a huge touch wall. The instructions are pretty detailed and fun to read and the cost is considerably less than buying a Surface computer (especially if you have a big rear-projection TV gathering dust somewhere). IDEO labs were not the first to do this they cite a similar blog posting at arbi.trario.us from November last year. Both systems use lasers and touch systems developed by the NUI Group - the ultimate resource for do-it-yourself touch screen enthusiasts.
