I actually tried this out, and it worked for me!
the wiimote is like 40$ and u dont have to make this entire nintendo wii thingy. Just the wiimote is good enough!
and then the IR pen is an average 9$... actually u can make ur own or try to mess with whats available online
if u have a mini projector u can make ANY surface a touchscreen(even ur wall)
if u dont have one, u can make ur monitor a touchscreen
and this guy gives u the software to calibrate it and it is free!
ANYBODY i showed it too went wow.. LOLZz and i didnt even have to do anything..
