This is actually pretty close to what I had in mind. Though, using a few simple image transforms you can correct for camera lens distortion and draw the keys straight-on, orthographically the way they are in the interface today (even if the camera isn't positioned exactly above).
Also, with some combination of chroma-key and image subtraction (from a still frame of the keyboard by itself), I expect I'll be able to have the hands drawn on top of note indicators/coloring, and still do it fast enough for real-time use. Really my only enemy is going to be input latency from the camera itself. Intel's OpenCV library can do incredible amounts of work in just a few milliseconds.

It would be interesting to find out if seeing your hands from top down rather than in front of you is disorienting or still helpful.

I think this would be an excellent idea. I am really struggling to use Synthesia at the moment because I can't judge the distance between the keys yet. Being able to see a video view (do they do widescreen cams?) top-down would be a superb feature.

Very interesting variations with this spam bot, I feel honored

That was a pretty good one. I wonder if my little anti-spam thing catches stuff in signatures too. We'll find out.
