Via MeFi,
60x1, a a web site consisting of a sequence of headfuckingly bizarre and fantastically elaborate splash pages (think WIRED Magazine meets the Book of the SubGenius or something), combining politics, celebrities, retro videogames, religious and Communist kitsch, crisp pixels, DHTML animation and bits of Japanese/Chinese text for good measure. And all this without a single bit of Flash.
Print them out, put them up and scare your family/housemates/coworkers.
