This afternoon, an NPR colleague of mine and I were almost arrested at Washington DC's Union Station for taking panorama photos with a Gigapan, a robotic camera mount developed by Carnegie Mellon University originally for the Mars Rover. The university had sent us a loaner of the robot for us to evaluate.
Though we were initially allowed to take photos, they unexpectedly changed their minds, demanding that we delete our pictures and cease taking pictures, or face arrest. They didn't seem to care I was Twittering their comments throughout the incident, though. I've posted a summary of what happened, as well as the resulting half-gigapixel panorama photo, on my blog.
