This is a very simple and fun way to make a regular canvas painting a bit more interactive. I recently moved to a small town in Scotland with my wife for educational reasons, and was getting a little bored in the evenings (everything is closed at 5, and I mean everything, hospital, police station, you name it). I was working on a painting for a friend who is a saxophone enthusiast and thought it would be cool if I could incorporate some of his music into it. This is a cheap project, about $20-$25 per painting. I apologize if this is not up to standards as other intstructables, since this is my first.
