I know they're only computer generated graphics, but maybe it's a bit miss-leading as to how it will actually look. Particularly like this http://thesupergoodl

Assuming the projector is mounted in the shelf, there would be quite a large shadow under where she is touching the wall. I guess the implications of this on such a small screen would be you'd have to pretty much figure out what you were going to press before you put your hand in front of the beam. We have Promethean IWB's and short throw projectors at school, trying to use them with your finger for precise menu operations is a nightmare. I think there used to be a keyboard that did something similar but it had terrible reviews
