How about books? Robert Anton Wilsons Illuminatus trilogy throws more strange nonsense at you in the first 100 pages than you could hear in a month spent in a nuthouse. Its got everything: secret societies, magic, elder gods, aliens, atlantis, and hippies in a yellow submarine. Its like having your brain raped for about 600 pages, but it feels so good...
If comics are more your thing, try picking up anything by Grant Morrison. Invisibles is a great place to start. I swear he was probably on acid the whole time he wrote it.
