Question about the MCL 2.0 examples folder

[timmons@lifesci.lscf.ucsb.edu (Bake Timmons)]

Hi, I've really enjoyed tinkering with the "turtles.lisp" file in the examples
folder.  Is there a more recent version of this (5/15/91) file?  The file
mentioned a possible future "saving-window" file (in the examples folder) that
could be used to refresh the screen.  Any help is most appreciated.  Thank you
for such outstanding work.
