The Fun Theory

Tired of all the cigarettes on the ground? This simple system is the solution. People will just have to put their cigarette litter in the hole of the "box" and thanks to a proximity sensor, it will display a funny joke on the screen that will make the people happier for the rest of the day, and they will speak about this joke or this concept around them. Thanks to this, more and more people will throw their used cigarettes (or paper) in that box.
In the end, this will save the environment and will contribute to the people happiness. Submitted by Fred Pigeard
