We've never been ones to call something obscene (unless we're talking about the price of coffee at Starbucks). Being called obscene, on the other hand—well, that's something we're old hand at.

So it was with great interest that we checked out the trailer for "Sex Art," a movie that examines the nebulous grey area of sex-infused art and arty sex, seeking out where, exactly, "obscenity" exists. With commentary from Betty Dodson, Eric Kroll, Eon McKai, Carol Leigh, and Julie Atlas Muz, the documentary offers a fascinating discussion of one of the most discussed, but never satisfactorily answered, questions of our time: what, exactly, is obscenity?
