A weird new gadget that plugs into a computer's USB port will...

...concoct a new smell based on the current song that is being played on the radio. It uses 6 perfume compounds which are then mixed together to generate the appropriate smell...The colored lights will change at random intervals for a more soothing experience, while the solenoid valve within sprays just the right amount of perfume in the air for you to catch a whiff.

The Aroma Joule will be sold in Japan (source of all sorts of weird fragrance items) for about $430. (via ubergizmo, link found on gizmodo via davebarry)
