At Burning Man, the annual arts festival, mutant vehicles plod across Nevada's Black Rock Desert. And this year's art cars include a fully-functional spider walker, a remote-controlled trilobite, and a mobile mammoth skeleton.

The theme of this year's Burning Man was "Evolution," inspiring a great deal of art, vehicular and otherwise, centered around the animal kingdom. On the more retrofuturistic side of things, this year's Burning Man also featured the "Raygun Gothic Rocket" as an installation, which, contrary to festival rumors, didn't actually take off.
