I'm not sure if this one has been posted before, and there's a good chance you've seen it anyway.
Amateur by Lasse Gjertsen is really a pretty good piece. Unlike, I might add,
Drumb and Drumber by Michel Gondry, which some people seem to have claimed that Amateur is a rip-off of. The fact that the latter is actually made by a guy with a lot of experience (amongst other thing, he directed Eternal Sunshine of a Spotless Mind), and is according to Wikipedia only 3 years old, makes the superiority of the former quite nice.
Lasse Gjertsen seems actually to be going somewhere due to that video and a couple of his others. There was an article about him in a magazine I subscribe to.
