Thanks for your interest in Copycat! Copycat is written in Common
Lisp. The system is unfortunately rather outdated: it will not run as
is without some updates for modern versions of Common Lisp, and some
platform-specific modifications to the graphics files. I am hoping
that it will be rewritten in a more platform independent way sometime
soon. I am still making the source files available.
To get the source files, go to :
and at your home machine, untar the file to get the source files.
If your system can't deal with tar files, then go to
and individually get each source file.

a Java version of Copycat and a tutorial; the web site is
