Happy Maps

In 2006 Adrian White, a social psychologist at the University of Leicester, compiled this, a world happiness map. You can get the full version here. The redder, the happier.

In a similar spirit, this little gem maps out 'feelings' from around the user-generated web and mashes it up with Google Maps:

It's not particularly powerful at the moment but is nevertheless a really interesting idea. I love the possibility of analysing subjective content over geographical location like this. If time were to be added in as well it would become even more interesting because you could potentially track the emotional wake of a certain news story after it breaks. Nice simple and playful interface too.
