Here is the final result of the Animated Permutation. The program uses the song Straight Heat by Edit (http://www.youtube.com/watch?v=1fcQNCY60vo) which is embedded into the program with the MINIM library. There are a nr. of things you can do with the program. You can Change the direction of shapes with the mouse as well as an override that moves that same shape with the keyboard from left to right (keys "k" & "l"). A inverse function with the keys "1". And a shape gets resized with the "m" and "n" keys. Here is the code and some pictures.
