Psyco http://psyco.sourceforge.net This presentation requires Python and Pygame to run. See http://www.pygame.org/ to install Pygame on your system. Execute accu.py to start the presentation. Tested on a Linux box, it should hopefully work on any platform. The document accu2004-psyco.txt is included in case it is of interest to you, as it contains a few things not found in the interactive presentation. On the other hand, the equivalent of the animated parts are pretty obscure in the text file.
