Can you imagine how this discussion will go when we have "real" VR? Holodeck-type stuff? "How can I make my scenes smell real? I mean, they smell now, but there's something indefinable that's missing. And how do you guys get that slippery, greasy feel so realistic?" "Have you gotten CL's Olfactometry upgrade? Not the 3.0, but the 3.0b? The slipperiness? You just have to practice with your friction settings."
