The LikeLight is a thumb that blinks for Facebook likes. It's made up of a custom lego set, arduino w/ ethernet shield, and a little PHP interaction with the Facebook Graph API.
During the build I hooked it up to LilWayne's Facebook page so it would blink a lot. It BLINKS A LOT!!! Like a strobe light! It's actually still pointed at his page because we like to see it blinking in the office. If you look close at the PHP code in the video you'll see his reference.
A little more detail on the build here
This was all filmed on my FlipHD I got for Christmas btw. Oh, and the song is a remix of All of the Lights (Kanye) su.pr/7yu4MR @hypem
