The face shown here is a visualization of bloggers' happiness in the past week.

When the face smiles, a blogger posted a sentence including the words "I feel happy."

When the face frowns, a blogger posted a sentence including the words "I feel sad."

The visualization is made possible by the data available at wefeelfine.org. Their site crawls all blogs on popular hosts, searching for the phrases "I feel" or "I'm feeling." This visualization distills that data down to a binary value of either happy or sad.
