Medieval colour mapping

My project was based on the idea of using an old painting and manipulate it with digital tools. I created a simple image loader (slideshow) and attached a snippet of audioplayer code on top of that for the background music. For-loop was drawing blurry circles based on the RGB colour values of the painting selected. The original idea was to control circles with music but I couldn’t get that work so I created mouse XY controller for drawing simple lines across the image.
