Animated GIF Extravaganza
Animated GIFs are all the rage lately, mostly because they can get through pretty much any corporate filter. I've collected quite a few of them lately on my hard drive, which I'll upload to a directory here someday, many of which I've found via GIFExplode's upload directory (warning -- many of them are not remotely safe for work). You can kill quite a bit of time looking at the oddball stuff in that directory.
If you haven't heard the story about GIFExplode, it's an interesting one.
