If you want to build an interactive programmable mirror, looks like Nanogest might be useful: http://www.nanocritical.com/nanogest/ It's available for both iOS and Android.

It recognizes 4 swipe gestures (top, down, left, right) and a wave gesture.

It's a library so you'd still have to build the information display part.

Thanks for the link! Is this really a state of the art right now? I was a bit disappointed when I saw the video... Gestures look awkward.

Beats me - I just wanted to see if a library like this even existed.
