Not collected all in one place. I think it kind of started with my daring Darth Logice into going further than his Angel for Mike morph. I've done one called MaterialGirl, Rorschach's got a Scully figure (Businesswoman), FairyWoods has the casts of Xena and Hercules, and AFAIK the rest of the lookalikes I've seen have been texmaps.
