World of Emotions
World of Emotions are attempting to map the feelings of the world. To register their emotions users just click on a happy, sad or neutral face and their mood is added to a Google Map of the world.
It is possible to refine the results on the map by different emotions. Users can view the positive, negative or neutral emotions on the map or view results for the last hour, day, week or month. The site also provides a table that ranks the world's countries by their degree of happiness.
