I keep coming back to this. It is a very creative idea. Reality effecting virtual reality. I wish you couldn't see the instuctions -"click and drag to smudge..." It takes the magic away. Also isure why you chose to have only black on the left?
The idea is interesting but from a photography point of view I find it boring. There's too much photoshop skill and not enough genuine photography skill used. For example your composition shows the windows Task Bar and even part of the System Tray - you could have at least cropped this out (I guess perhaps it was a deliberate inclusion)
