I was experimenting with abstract art and vector maths to simulate shadows from an artificial light source. In this experiment the source of light is controlled by the horizontal position of the mouse cursor. It was inspired by a CD cover I saw somewhere. Here is a sample screen capture:
You can see a unique sequence of the live running code here:
Also here is a black and white variation on the above that has no shadows but is still interesting on its own.
Here is the running code for it:
