Jonathan Harris and Sep Kamvar made a web based collaborative art piece in 2005 titled We Feel Fine. I remember hearing about it at the time, but I’ve only just gone and checked it out. The project, located at www.wefeelfine.org presents a database of feelings, captured automatically from blog posts. Essentially the system searches for the phrase “I feel”, when it finds such a phrase it queries the text to discover what feelings are being expressed (i.e. happy, sad, ok, suicidal, etc.). This information is then presented as a “particle system”. The result is impressive in its scope and execution. After playing with the swirling mass of particles and clicking through to the various expressed feelings and related blogs I feel, well many things, but mostly quite small. As it turns out, so do a thousand other people.
