I caught this at AICN. Not sure if this is old news around here, but I didn't see any recent threads on it...
This is the shrunken YouTube version of a 70mm test sequence from Hayao Miyazaki (and directed by Yoshifumi Kondo) for the proposed Little Nemo animated movie. They eventually pulled out of the project, but not before making one of the most astounding flying sequences ever to come out of the Miyazaki factory. Keep in mind that this was done in 1984...all of that is HAND DRAWN. Ignore the dumb narration at the beginning and end. Just bask in one of the coolest YouTube clips you'll see this year...
