PDA magic window

Overview

Using a PDA as an auxiliary display for a computer/laptop[1] but taking a step further than that. By combining the guts of a wireless optical mouse or something similar to change what is being viewed on the auxiliary display in relation to movements made over a surface. The PDA would still retain it's input capabilty of the touch screen and possibly buttons but on a remote display. Ideally you would use this device to connect remotely back to your pc/laptop and use any available surface area(wall, desk, etc.). Essentially we're making a wireless optical mouse with a touch screen and remote desktop display/input capability.
