Tweetlite flashes Twitter messages in Morse code
“Tweetlite” is a Arduino-powered plexiglass cube that displays a person’s Twitter stream in LED flashes of Morse code. That would probably drive me nuts (although its creator Bruce Drummond does make a good point about its usefulness as a Morse code learning aid), but I’ve always been a sucker for ambient lights communicating status, even if in practice it can be a bit tedious.
