Brian, aka Plasma2002 of San Francisco build this LED scroller that displays messages SMSed to a Google Voice number.
I’ve always loved the idea of sending messages to the big screens you usually find at concerts and other large events. I figured it could be scaled down, while still being just as entertaining. It may not have one of those spiffy 5-digit phone numbers, but the Google Voice number that it uses works just as well – especially since it also works as a vanity number for my handle :)
After testing the sign at a party held at home, I noticed that people really seemed to enjoy it. One part of it that led to people enjoying it was the fact that the messages were anonymous. While it would have been really easy to make the sign show who the message was from, if theres one thing I’ve learned from the internet, it’s that people love being anonymous. Leaving a message that your peers can see, without knowing who wrote it, will always invoke the most curious behavior.
