I suspect it's less about the music and more about the finger tracking, but to the extent it's about the music - billions of people have smartphones with cameras that would work with this code, but would unlikely be able to afford piano lessons or convince / inspire anyone to offer to purchase them an instrument without first demonstrating aptitude in some area. Definitely not intended at a dig at you and hope you manage to hook Mayuresh up with a keyboard instrument and a job!

Phones have touch screens that are better touch-based MIDI controllers than paper+camera :) I've successfully played songs on phone pianos.

However, neither solution is even close to a tactile instrument.

You are absolutely right, my intention behind it was that you could really play the piano not on a small screen (like a phone) but like an actual sized piano. I didn't want to buy one because they were expensive and I am more like "free is the better" guy. So I decided to make one on paper. This being rather a prototype, I am currently working on designing and mapping keys, improving upon touch recognition. ( also I have mailed you )
