Adding to the ever-expanding multitude of USB-powered thingamajigs is this Smartech USB Aroma Radio + Speaker. It lights up your abode with seven soothing colors while playing music from its internal AM-FM radio, or lets you plug in your iPod or MP3 player to give you more control over the musical atmosphere.
Up top is an aroma oil burner that'll fill the air with your fave scent, further stimulating the human sensory array, eschewing only touch and taste. But we'll leave that part to you. If you don't mind its nuclear cooling tower-like looks, it could be a sound investment of your $30, maybe enough to change a "maybe" into a "yes."
