Absolut Panushka - visual music
For less than a year in 1997 there was a wonderful website on experimental animation, Absolut Panushka, (sponsored by the vodka company) curated by animator Christine Panushka. I don't know why, but the site was taken down.Many of the fifty short essays on animation history, by William Moritz, can be found here now. They are an excellent resource for background on independent and abstract experimental animation.
