Idea:
Create bar-code paintings from poems, novels, and train-schedules. When showing these black and white paintings, lend people bar-code readers to decrypt them. The scale of the paintings could range from very small, 1′ by 2′, to very large. Could be an interesting project for Subway Station Murals? Would a bar-code reader work on large scale bar-codes? Or would it have to be modified? Look into computer programs that transfer words into bar-code. A projector attached to the computer would make it easier to paint the bar-code.
