an impressive collection of beautiful data visualizations that depict human feelings & moods harvested from a large number of weblogs. a system searches the world's newly posted blog entries for occurrences of the phrases "I feel" & "I am feeling", records the full sentence & identifies the "feeling" expressed in that sentence (e.g. sad, happy, depressed, etc.).
the different data visualizations consist of a self-organizing particle system, where each particle represents a single feeling posted by a single individual. the particles' properties (color, size, shape, opacity) indicate the nature of the feeling inside, & any particle can be clicked to reveal the full sentence or photograph it contains. the particles move wildly around the screen until asked to self-organize along any number of axes, expressing various human emotions.
