Check out the video below and watch the lamp built by Adam Ben-Dror, Shanshan Zhou and Joss Doggett, interact with people and its environment using its mechanical servos and built in webcam with facial recognition/tracking software.... well done :)
Powered by an Arduino, a hacked webcam, a mechanical iris, and a set of servos to move it about, the lamp seems curious of its environment, particularly humans, thanks to software that recognizes and tracks faces. It even appears to be capable of playing peek-a-boo, looking rather distressed when it's not getting attention from someone sitting nearby. And it hates being put to sleep, so it will adorably switch itself back on when you try and power it off.
....Very awesome and Very creeeepppy. No word yet on if it watches you while you sleep..!!
