The note from Joi Ito’s web about the arrest of the organizer of something called Bikes Against Bush is interesting (aside from the fact that you can get arrested for being in NY with a bicycle nowadays.)
The technology of the dot-matrix printerbike is very cool, but isn’t it a little too complicated? I remember reading from one of Hemingway’s books about people walking around the streets of Paris with a rolling drum which would paint the word “Cinzano” on the sidewalk in water – which would, eventually, evaporate, hence no need to clean up at all.
This bike, ingenuity aside, strikes me as a high-tech answer to a low-tech problem. Still cool, though.
