I just wrapped up work on a visualization for the 2009 Last Supper Festival. The work visualized a series of conversations during a symposium on the topic Identifying Our Means. After three short presentations, four groups were formed to discuss a number of topics, periodically rotating the group members from one table to the next. At each table was a note taker who recorded as close to verbatim who was saying what and when, with the help of an automatically time-stamping spreadsheet.
Once the data was collected, a number of scripts were written in Python to extract, convert, clean, and export the data in addition to performing some basic analysis. Finally, I used the Prefuse Flare library to create an animation at 40x real time of the interaction between people and key topics. Below is a still frame from the animation.

Special thanks to David Friedlander, Chris Kennedy, Stephanie Nikolopoulos, and Reid Rogers for collecting the data (taking notes) during the event!
