Here's an audio presentation by Theo Jansen at PopTech 2005. Jansen is the creator of the
amazing beach creatures that we've covered before (which happens to be our most popular post). Jansen talks about his creatures and how he started creating them. Unfortunately, there seems to be a significant visual aspect to the presentation that you'll just have to use your imagination for.
Theo Jansen is the kind of robotocist that Leonardo da Vinci would have been if he'd been born 400 years later.
The presentation is 36 minutes long and quite interesting if you're interested in genetic algorithms, computer guided evolution, and just plain ingenuity.
