I dig electronics, remote controlled cars and iPhones. A couple of summers ago, I got really excited about the idea of building electronics that I could control with my iPhone. By connecting a router to an RC Car from my childhood, I wrote an iPhone app, and built a RC Car that could be controlled from the iPhone's accelerometers. Then one night after a few beers - Gabe and I came up with the idea to add a camera that would stream video back to the iPhone.
But I'm not the only one who likes building electronic gadgetry. During a recent Hack Day at Yelp, Julian, Bakun and I teamed up to decorate the office with a hand made Yelp burst. In the video you'll see that it lights up every time a review is posted to the site - and it flashes with the corresponding star rating of that review (three flashes - three stars). OK so it doesn't turn corners like the IC car (iPhone controlled), but it looks damn fine in our work space.
