If I were to tell you “I have invented a mechanical animal made out of plastic tubes and that roams the beaches only using the power of the wind” you may look at me a little strange. So when Dutch artist/engineer Theo Jansen describes his kinetic sculptures he would get some odd looks indeed. They have to be seen to be believed. They are a triumph of light-weight design, alternative energy sources and of thinking right outside the square (things that we rate highly here at Pli). He has even created a simple brain that controls these graceful beasts. This is only an 8 minute talk; even if you just skip through it it is worth the watch.
