LikeLight lights up your likes with Legos, Arduino (video)

How long has it been since someone lit up your life? Since someone gave you hope, to carry on? As it turns out all you need for that is a box of Lego, an Arduino board, and a bit of your time. Ad agency Redpepper has successfully proven its abilities to generate buzz by creating this "LikeLight," an up-scaled version of the blue pixelated thumb that makes Facebook denizens get all in a tizzy. This bigger version is almost guaranteed to generate even greater tizzies, glowing blue thanks to a combination of clear bricks outside and four LEDs inside. Code is even provided that pulls data from the Facebook Graph API to light up those bricks -- and your life.
