Speaking of which, there was an artist named Poseidentech that used to make really elaborate "anatomically correct" character and detail morphs for V4... I have most of his character sets, which included also extensive/obsessive boob morph options. Anyway, he used to have his own site, not sure if it's still up, and he had animations of his genital movement morphs on V4. Pretty weird and hilarious, like phonemes but down yonder.
