A pay site containing a (claimed) large collection of stills and video captures of "the good parts" (as the site's author so succinctly puts it) of movies -- the nude scenes.
"Mr. Skin," not his real name, of course, gained a good amount of publicity from several appearances on the Howard Stern show (radio and TV), dishing out the nudity dirt on all our favorite celebrities.
Last year the site acquired a similarly-themed site, the Celebrity Nudity Database, which doesn't contain pictures, but is free, searchable by actor/actress or movie, and accepts reviews from its users.
