Marcell Jankovics kicks ass and comes from Hungary. His Fehérlófia aka Son of the White Mare is quite a jewel among the videos posted here so far, because it is a feature length animation done in non-stop psychedelic style! Playlist link.
A more recent feature by Jankovics, Ének a csodaszarvasról / Song of the Miraculous Hind (2002), has shamanic episodes, which are done in a style that reminds me of Huichol art. The Youtube version has sucky picture quality and no subtitles, but if you’re not put off by this you can find the rest of the movie by clicking “Watch in Youtube” and looking at the related videos or in the uploader’s channel.
