RNC protests: Bikes Against Bush organizer arrested

Dot Matrix PrinterBoingBoing 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.
