The Fun Theory

So many gloomy faces can be seen nowadays on bus, tram, we can meet angry car drivers and rushing masses on the streets. One smile can break this negative wave. Smiling is good to our body and soul, and it also generates a chain reaction: if you smile to someone, he will instinctively smile back. The theory is that a chocolate automat is working with smile. The core of the automat is a face recognizing software that decides if someone smiles or not. Also with this program only one chocolate per person could be given. Submitted by Edit Tangl.
