Things on this site:

Something Awful iChat Smiley Pack: Replaces your iChat smilies with better smilies. Only works on OS X 10.3, because I never get around to updating it.
Episode notes for (the first four episodes of) GunBuster
"The World's Best Flash Animation". (not written by me)
GPL violations in Ico; I'm much less angry about them than Slashdot is.

Other sites:

iThink Software makes shareware for OS X.
Jared Fager has a website. He makes things… art, I think. (note: doesn't actually have a website)
Shii is a cat in a box.
Joseph Spiros isn't a cat in a box, although he has some cats and some boxes.
Something Awful sure is something awful. (my siblings are covered in wax)
