Imagine Christian Marclay's multi-channel movie mosaic masterpiece, Video Quartet, but done entirely with anime--and with a little bit of narrative laid over the top.
That's Istiv Studio's The Race, which is made up of clips and rotoscoped characters from over a hundred anime films, laid over a Weezer soundtrack. A pretty awesome way to spend a year of nights and weekends.
