This was the biggest one, with the FMA kitties and several other pieces I recognize at least vaguely.
This has one I recognize and a few that look like fanart from somewhere or another.
This has just a couple familiar ones.
I know there's things I didn't catch, though... Any rate, the site's TOS does state that claiming someone else's work is against the rules (in here). There's pretty specific guidelines for reporting in there.
