Rain dance

First heard about these guys on ABC's Nightline. It's a new phenomenon (or not-so-new, growing organically out of break dancing, mime, Michael Jackson's moonwalk, and Shields and Yarnell's robot routine) called turf dancing, with sudden, spectacular leaps and jumps and flips. This was also called the rain video, in memory of Rich D, of whom I know almost nothing. This is a phenomenon of Oakland, California, for reasons unknown. A "how do they do that?" sort of thang.
