In July 1996 the Brain Opera, a collaborative, interactive, sound and image event based on Marvin Minsky's seminal book, the Society of Mind, opened at Lincoln Center and on the World Wide Web as part of the 1996 Internet World Expo. This project continues to tour in the U.S., Europe and Asia. The final version will be permanently installed at Vienna's new "House of Music"
in July, 2000.
