File under "shameless promoting of somthing I think is really cool".
The Image Of The Day at The Cellar is almost always incredible. Tons of really cool/interesting/disturbing pictures and Slashdot-like comments on each. Well worth a visit. Check the archives for a ton of pervious posts.
Oh, almost forgot to mention, I submitted an IOTD (that I found, not that I took) a while back and it was accepted. Of course, I wasn't a registered user of the site, so it was credited as "anonymous". But I still get credit.
I may have to give The Cellar a perma-link on my blog.
