Funny to see this, I made more or less the same thing in Processing for the google devart interactive competition a few years ago: https://www.youtube.com/watch?v=YaA3dAJz6sI&feature=youtu.be

Has a few extra features like being able to see different visualisation methods and how basic colour correction influences those - also animates the visualisation while going through the image

Realluy caught me off-guard because I used both the starry sky and the monalisa painting back in the days as well!
