It's sort of like Memento (if you ever saw that movie), except with a guy reverse-destructing rocks.
that was damn cool. i wonder how he did some of that stuff
It looks like they built up rock sculptures, then destructed them. They then played back the destruction in reverse so it looks like they're building it up.
yeah, but he must have practiced doing things in reverse, because it looked much more natural than a normal play backwards video. like when he "walks away" from a pile after "rebuilding" it, the motion only seems slightly jerky.
