Hyper is a photograph collection of breakdancers (well, I'm not positive if they are breakdancers) floating in common places like convenient stores done by French photographer Denis Darzacq.  Link to gallery.  La Chute is another one of his collections.  It's worth the look. 

Check out this fun stop-motion hip-hop dance off video.  The camera work is a little shakey, but still worth a look.

Ok, not sure if this has been posted yet or not.  And I know Ebaumsworld is lame, but check this little kid out, he's rippin it up old school.
