This videotape is available as a single Real-Player segment
as well as Quicktime (seems to work on Unix machines but not
Windows...) It is at half-size (320x240 pixels) instead of full
video resolution. I have put separate downloadable and streaming
realplayer versions. If none of these work, you can try looking at the
SIGGRAPH 2001 conference videotape. The video length is 5:35 minutes.
