In this 4 minute video, made on KTU3, I flip through a bunch of slides (oops on the loud woosh noise), talking about the presentation manager plus the content of that talk (about two years ago as of this writing). Mainly I'm testing Camtasia Studio, a tool for building screencasts. The slide show ends with an embedded segment of Bucky Fuller (just a few seconds). Wanderers mentioned. Polyhedra.
