Will we ever be able to approximate scent digitally?

We can already reproduce sonic and visual elements, and there are products out there, if you're so inclined, that vibrate and otherwise create motion. So that's three of the five major senses. Do you think they're working on an electronic means of creating scent? How do you think they would do that?

dunno - we've had scratch and sniff before so who knows???

But scratch and sniff faded so quickly...I used to have one of those books. It was a good one. I think I scratched all the scent out of it within a few months...
