The Fun Theory

Problem tackled: Reducing the cigarette litter in front of public places.

Solution: Make it fun to stub out a cigarette in an ashtray. On the tray is mounted a video screen equiped with some kind of heat sensing. The cigarette butt is used on the screen as a paint brush. The color of the "trait" depends on the heat sensed. The color degrades in time creating a dynamic painting that evolves continuously.
