Mark Fauenfelder is the founder of Boing Boing, a culture blog that deals with topics on makers, technology,DIY and a bunch of other cool stuff. He appears on Colbert as a guest, which was awesome to begin with. On the show he, shows some of the awesome things he has made for himself and others. One of the devices that caught my attention was his Twitter Orb. The device is hooked up to an arduino with wifi connectivity and scans twitter for key words. During the interview, he made it scan Twitter for posts that included Colbert in it. Everytime his name was tweeted, it blinked! I think this is great because its a way to visualize information in a way that is different from your standard smartphone notification.
