babybiomorphs

Biomorphs are a way of explaining evolution invented by Richard Dawkins. The shapes are controlled by a small set of genes, which give colour, segment length, size, and degree of recursion.
By changing a gene by a small amount, a small difference is made in neighbours. Many fascinating shapes can be found, and you can often home in on a desired shape by selecting relatives that are closer to your goal.

The program uses the Baby X toolkit.
