Thanks for sharing this.

There are also some cool programs at Processing.org that do similar kinds of things in Java, Python and Javascript.

I love that thing. I rewrote it in C++ a long time ago. I implemented a genetic algorithm for all of the springs and lengths and stuff so it evolved a super fast runner.

Cool! GA - that was the idea of original author of Soda as well. Did you capture some videos of these evolutions? Was it hard to control? It's extremely interesting to me :)

No unfortunately, I didn't. I remember I used the "Dainty Walker" as a base, and evolved from that. I remember that the front legs got shorter and the bag legs got bigger and more powerful. I just let it walk across a randomized terrain and bred the 50% that got the furthest.

An interesting variation would be to develop an app that simulated the Interstellar robot TARS' gait.
