Now here is something cool from my alma mater, Carnegie Mellon University!

PRESS RELEASE, May 13, 2010: Carnegie Mellon Professors Launch Billboard Featuring Overheard Conversations
PITTSBURGH—The long defunct billboard structure on top of the Waffle Shop building has been redesigned into a large, analog Twitter account, presenting overheard conversations from the restaurant and art space below. Instead of seeing a typical commercial advertisement, passers-by now see a set of custom-made letters with only the sky as the background, creating a live marquee that can change on demand. The concept is the brainchild of Carnegie Mellon University professors Jon Rubin, an associate professor of art, and Pablo Garcia, the Lucian and Rita Caste Chair and an assistant teaching professor of architecture.
