BoingBoing reports that Joshua Kingberg was arrested at the RNC in New York for operating his bicycle mounted dot matrix printer. It’s an enormously cool hack: you basically ride the bike and it leaves a message in its trail in the same way a dot matrix printer works. The message is written in a water soluble chalk solution which washes right off. A very cool idea, and a pitifully sad day for free expression that he was both arrested and his cool gizmo confiscated.

But then the RNC is not known for its humor.
