Information about this Document
Everything here was done on a Sparc 5 workstation,
at the University of Chicago.
I made the pictures for this document with
XFIG, a drawing program for X Windows.
After drawing a picture in XFIG, I would export
it as a GIF file.
To animate these pictures, I used a C program called
GIFMerge . This program can be downloaded from
Eventually, I would like to use Java to create animated
pictures for this document.
