The first semester of our Freshman Research Initiative on genetic algorithms for pattern design ended May 2011. Students from the CS and Fashion departments were teamed up and spent the semester building algorithmic patterns that can be bred by users to find interesting patterns. The result is the below app.

Mouse over to see a larger pattern.
Left click to breed that pattern and see a new set similar to it. Be patient, it sometimes takes a while to render.
Back and forward buttons to navigate the previous generations.
Random to create a new random generation.
