I have to bring up this scene in the movie Gattaca. Jude Law (a disabled man who is illegally loaning his good genes to Ethan Hawke, a man with bad genes): "What's Titan like this time of year?" Ethan Hawke: "What's Titan like? Titan is exactly like this... [He blows cigarette smoke into a wine glass, and the smoke erotically folds and unfolds above the wine at the bottom of the glass]. All the time, it's got a cloud around that's so thick, no one can tell what's underneath." With Touch Screens, we do know what's underneath: cocksucking, fucking, fingering, tonguing, thrusting, humping. But all we see (or hear) is the thick swirling, moist cloud above these graphic images.
