Dyson AM04

Like a good assassin, Dyson's AM04 is both silent and seductive. The 22.8-inch-tall oscillating fan operates by drawing air up through its base and firing it from its ring in a smooth, continuous stream. More than a mere fan, it has an internal thermostat that ranges from 32 to 99 degrees, so you can tweak its settings to fit your needs for both summer and snow-blanketed days. [$400; dyson.com]
