Have you ever seen Granular Synthesis? <http://www.thing.at/granular-synthesis> I saw their Modell 5 at a Recombinant event a few years ago. 44 minutes of stuttering image and sound projected onto four large screens. Not pretty, but powerful. There are several programs, such as Videodelic, for live image manipulation. As Rick points out, the major problem is the price of projectors. -- ______________________________________________________________ Richard Zvonar, PhD (818) 788-2202 http://www.zvonar.com http://RZCybernetics.com http://www.cybmotion.com/aliaszone http://www.live365.com/cgi-bin/directory.cgi?autostart=rz
