Some great stuff here!
Dig Pink Noise... and have you perused the philosophy books page? I like the look of it, but wanna know if you've read any of those and could tell me a lil' about them.
This Is Not Porn is great, too... crazy site. A lot of stuff like this would be done with flash back then, so I'm glad they used another method since flash got kilt a few years back.
Kalx and Park.org are great, too!
Respect to CNN for keeping that page up!
Heaven's Gate is another classic you mentioned, reminds me to mention the Church of Ed Wood.
