its a short by Don Hertzefeldt (hope i spelled it right), who also made the excellent animation 'it's such a beautiful day', which is one of my all time favorite movies. also made the animation 'world of tomorrow' which is probably some of the best speculative sci-fi i've seen.

minor bit of pedantry, despite the simplistic stick figure art style its distinctly NOT flash animation, he does everything analogue (paper and an old school photograph machine) which allows for some wild visual techniques and mixed-media stuff.
