USB Fragrant Oil Burner
I enjoy the kind of aromatherapy oils that you burn with a tea light candle, but I am continually scared of setting the house of fire by forgetting to blow out the candle or just leaving it unattended. This device uses the electrical current in your USB port to heat the oil and scent your home.
For $19 you can add the scent of lavender, orange or patchouli to your home with the use of your favorite oils. This is such a product for hippies and geeks alike. I am strangely tempted by it, despite my overloaded USB ports.
