Images and their Secrets

This is idea number two. The core idea involves reading in an image (possibly room for Google Images API) and then generating a few 'species' on the image which will feed off it's colour information. The image will lose saturation as it is eaten, and the species will evolve/adapt various traits based on the colours they have been devouring. When coming into contact with each other, they will fight, and the outcome of battle will be determined by their traits.

It suggests that images have a secret hidden world of activity going on behind the scenes.
