These Gesture Controlled Lamps use the Arduino Microcontroller to detect movement and adjust the lights accordingly. If you want to get your hands on a free Arduino microcontroller have a look at the latest uC Hobby giveaway.

“Gestures in front of any lamp affect all the lamps. The lamps all show the same display, but it depends on which lamp generated the triggering event.

For those of you new to the project: the concept is “action at a distance”, the lamps all react in unison regardless of distance (well, within a few hundred meters). Technically, quite complex: uses AD5206 digipots, Zigbee radios and Arduino minis, all held together with some elaborate software.”
