Nanites?

Really interesting things being done by very small robots working together, but I can’t help but think of nanites from Star Trek TNG and the swarm from the book Prey by Michael Crichton.

This video is about 2 minutes, 40 seconds long. I think it’s worth the watch. It’s one of those if you try it for 30 seconds, you’ll want to watch all the way to the end.
