Mardi Gras flower from Rick Montgomery on Vimeo. This "flower" was produced by a genetic modeling algorithm that creates random shapes, then makes a lot of slightly inaccurate copies of them and scores the second generation for various characteristics of color, size and shape. Then a few of the top scoring members of the second generation are selected as the progenitors of the third generation, and the process is repeated. After a few hundred or a few thousand generations, you wind up with some interesting shapes.
