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.
