pottercw writes "Good summary of today's touch-screen technologies on Computerworld — the obvious Apple iPhone and Microsoft Surface, plus projected touch screens (nothing for users to break), handheld devices that you control from the back (so your fingers don't obscure the screen), and of course giant multitouch walls a la Minority Report. Anyone got $100K?"
I don't have $100k but I do have $40, a web browser and a basic knowledge of electronics. If you do too you might want to try this link.
