Here is some of the best stuff I have found on YouTube recently:

(Link if you’re reading in RSS). This is visualization of a DJ scratching. The “how does it work” is pretty neat.

(Link if you’re reading in RSS). I think I would categorize this as Machinima. It’s made using a web-based Flash game called Linerider. Play with Linerider for a little bit to appreciate how difficult this must have been to make.

(Link if you’re reading in RSS). I often cruise through the timelapse tag at YouTube, and this is one of my favorites.

(Link if you’re reading in RSS). Wes Anderson is one of my favorite directors. This commercial is shot the same way he ends all his movies: a long, highly coordinated cut with characters popping in and out of the scene, yet the whole thing flows as the camera cruises along… very cool.
