The post title links to a live Saudi web cam trained on the ka'aba in the so-called "Grand" Mosque of Mecca. Watch the swarming ummah at your leisure. For additional background on the ka'aba and the black stone go here or here or here. If you didn't think before that Islam was a creepy cult of ancient tribal superstitions, mated to a barbarous and superficial understanding of Judaism and Christianity, you've got some work to do. And be sure to click-up the links, especially this one.
UPDATE 6/16/2009
It appears they've shut off the web cam, leaving the page there, but without the swarming image. It was a live version of this....
UPDATE 6/18/2009
The web cam is back up.
