Building rock formations

This is a link to a fairly cool video, shot in reverse showing what appears to be the unassisted assembling of small rock formations. It's clear how it was done...simple enough to run video backwards, but it's one of those videos that is entrancing to watch. It has a zen quality. It starts slow... so wait for it.
