Banksy
I'd never heard of this London-based artist before I read about his interesting "exhibit" at the Natural History Museum. Anyway, I thought he would be your usual pretentious modern art shithead fop but actually turned out to be a very interesting artist, who does some very cool work around London. Here's a link to his site, which has a very interesting navigation.

Retro video games
Do you remember the classics? Not the silly classics like Pong and Space Invaders. I'm talking about the REAL classics - games like King's Quest, Alley Cat, Boxing and Paratrooper.

These are the games I first played when I was little kid on my dad's IBM PC XT in the mid-80's, and you can download most of them from this wicked site called Home of the Underdogs, which is dedicated to preserving and archiving old skool games.

It's really worth a look.

This is too cool.
Subservient Chicken is this website run by Burger King (to tie in with their "have chicken your way") concept which involves a real-live actor that will do anything you want him to. My favorite thing I got him to do was "do your best impression of Jesus". He got on his knees and wailed.

This is the most original site I have seen in ages.
