There are already a few USB-powered room fragrance gadgets, but to my knowledge this is the first done up with plastic flowers.
The USB Scent Flower comes in four scents…
Aroma Joule concocts fragrance to match your music…
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)
