Facebook has pretty much wedged itself firmly into every aspect of our daily lives - businesses have pages (like SparkFun's), bands and politicians have joined the party, and of course, your friends and family are probably there as well. In case simply having a profile to show how many "likes" you are racking up isn't enough, I present a neat project called "LikeLight."
Using an ethernet shield, an Arduino, a whole bunch of Legos, and a connection to Lil' Wayne's Facebook page, redpepper built a pretty cool project in the shape of the Facebook "Like" button. Whenever anyone "likes" Lil Wayne's Facebook page, this thing illuminates. Apparently Lil' Wayne is really popular, because this thing goes off like a strobe light. I guess I'm just not "with it" these days. Check out the project page for more information to build your very own LikeLight!
