Have you met Huey? Huey is a chameleon shaped LED lamp. Like all chameleons, Huey can change colors. Simply put this lamp on top of a color and he will change his hue to match. Hue, Huey, get it?
If you don’t know what color you want, or don’t have something that color handy, Huey can cycle through all the colors. To set the color, whether he’s cycling or on top of a like-colored object, just give Huey a squeeze. Runs on AAA batteries or AC adapter (w/a long cord). $29.99 from ThinkGeek.
