I wonder if you could also rig up a few microphones to enable touch controls.

I remember reading an early Stephenson novel, where a stereo system was described as a blank black slate, with essentially invisible controls. Having something like that behind a mirror would be a fun hack.

It depends on the thickness of the two way mirror, but you may be able to get touch by removing the protective glass from the android tablet so that the digitizer is in direct contact with the mirror.
