Actually, it
used to be the case that Mod Detectives wouldn't be the thread for this - there
was also "Mod Psychics" - but these days, that remaining thread [series] is for both kinds of question.
I mean, if anyone else wants to reply here anyway, I'm not going to try to stop them or whatever.

Just thought it was worth clarifying, in case you didn't already know.
edit: Oh, and as for what you asked... sorry, no idea.

Hm, except some of the eyes used in the full RBP - they're "photorealistic" (i.e., actually from photos). I'll see what else comes to mind, if anything.
