Haircut Mouse. A short animated film by Michel Gondry.
Neuro is a new Flash cartoon by Bruno Bozzetto, an Italian animator most well-known for creating the character Mr. Rossi. In 1965, Bozzetto was the only Italian to create and produce an animated feature film in over 20 years. Check out the rest of his excellent site, which includes a bio, clips from his older work, and some more recent Flash cartoons. I recommend the short Europe and Italy.
