There’s a bit more involved with this one than just a Wiimote, however — namely, an IR-emitting pen (or two), which the Wiimote tracks while relaying all the necessary information back to a PC. That, as the video after the break shows, allows you to turn any surface into a multi-point whiteboard with the use of a projector, or turn any LCD screen into a touchscreen
