Mappiness

I nifty British experiment has begun to map happiness using iPhones. Mappiness pings iPhone users who have signed up for the project several times a day to ask them how happy they feel and what they are doing. The phone will also tell the researchers where the respondents are, and the time of day. The research project can them map which places are happiest, and what sort of features those places have. The app also keeps track of the users responses over time, creating personal happiness graphs for each person.
