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.
After seeing Jud Turner's skeleton bike the other day, it's clear that he has some things going on in his head. Scary things—like this "Trilo Temporalis" trilobite fossil clock.
Its carapace has turned to steel in the hundreds of millions of years since it went extinct, but the watch in this Trilobite's brain never stops tracking the seconds passed since the Cambrian ended.
