Can’t say this is new, but its super cool.
Since August 2005, “We Feel Fine” has been harvesting human feelings from a large number of weblogs. Every few minutes, the system searches the world’s newly posted blog entries for occurrences of the phrases “I feel” and “I am feeling”. The result is a database of several million human feelings, increasing by 15,000 – 20,000 new feelings per day!
Each particle represents a feeling from somewhere in the world, so click on them and go wild!
You can change the way the data is sorted at the bottom left corner to get a different representation of the feelings!
