What Is This?

Wait, is NASA making weather balloons shaped like a giant Rubik's Cube now?

Nah, it's one of the many art installations sprinkled over the dusty playa at Burning Man 2009. This year's theme is Evolution: A Tangled Bank. Safe travels if you're a weekend burner headed to the Blackrock Desert, and don't forget the distilled white vinegar to neutralize that alkaline playa dust!

One year later (and having travelled around three continents since), that stuff is still turning up in random places like my hiking shoes. [San Francisco Chronicle]
