Each time the program is run, an initial population is created with 50 individual designs — each with random values assigned to the eight parameters. You then rate each individual design before evolving the next generation. The algorithm chooses individuals to carry on to the next generations (highly rated designs are more likely to be carried forward, but low rated designs may still be used).
Each of the eggs in the photo above was printed from the same program with waves evolved from random seeds.
Congratulations to our friend RobotGrrl, who took home a gold medal in the Best of Show category.
From the White House Office of Science and Technology Policy blog post, An Egg-straordinary Day of Science and Technology:
Interacting with EggBot, an art robot that can paint very intricate and precise designs on eggs. EggBot taught students about digital design, computer numerically controlled machines and robotics. This was also a fun way to celebrate National Robotics Week!

She’s posted some beautiful eggs, drawn on with a variety of pens.
There’s a fun series of ping pong ball gifs.
Happy St. Patrick’s Day! Thanks to A.Z. for sharing these photos of ornaments decorated with shamrocks using the EggBot.
