Not directly related to nanotechnology, (afaik) but totally awesome are these two quantum mechanic videos for magnetic levitation: http://www.youtube.com/watch?v=VyOtIsnG71U
and even weirder showing superfluids: http://www.youtube.com/watch?v=9FudzqfpLLs
While I am not bad at understanding the basics behind the nano-tech physics, my mind kinda goes fuzzy over quantum mechanics.... but the superfluid vid is awesome, just imagine if you were holding a bucket that definately had no holes, yet the liquid still escapes by creeping up the sides.
