Great strides are being made toward that Holy Grail of olfactory goodness: Smell-o-Vision. First we heard about a scent recorder, and we've seen various USB stenchers, but now here's the USB Aroma Joule, reacting to sound and spewing out appropriate odors for whatever music it hears. At the same time, it gives you a cool-n-funky disco light show.
Connect it to your PC's USB port, and its accompanying software figures out what aroma is appropriate for certain kinds of music, spraying its scent in the air using an electromagnetic solenoid valve. Just peer into the innards of the thing! It looks like an evil brain from some science fiction movie. Available October 2, it'll be $430.
