Announcing the official public release of Copy Cat 2.0:
a mimicry simulation

Copy Cat is a program I wrote for the Macintosh interface that produces a 
natural phenomenon called mimicry.  Mimicry is actually quite a 
complicated and so-far not completely understood occurance in which one 
organism seems like another organism (generally in visual appearance) to 
the end of benefitting from the likeness in some way.  This is a classic 
exploitation scheme, because the mimic is always getting away with 
something, evolutionarily speaking.

In November, 1995 I finished Copy Cat 1.0 which was such a tremendously 
complicated system that I couldn't figure out how to tweak it into 
working.  Since then I have slaved over the code and in the past few 
weeks have perfected the process of simulating mimicry.  Version 2.0 now 
confidently produces mimicry nearly every time a new simulation is run.  
The interface gives the user far more control over the program than they 
need in order to simply produce mimicry, such that simple experiments can 
be carried out with the program once one becomes adept at the controls 
and confident about the workings of the program.  A rich display of 
graphs and histograms show all the data necessary in order to demonstrate 
the occurance of mimicry in the system and extensive documentation is 
provided.  I believe that anyone who takes the short amount of time 
needed to learn how the Copy Cat environment operates will have no 
trouble using the program and seeing how remarkable and unmistakable the 
results can be.

Copy Cat 2.0 only runs on a Macintosh computer, requires a color monitor 
and may require Color Quickdraw and system 7 (I'm not sure).  It is a Fat 
binary application and thus will take full advantage of your Power Mac 
while still running rather impressively on your 68030 or 68040 (possibly 
68020s too).  Regardless of which computer you use, no floating point 
unit is necessary to run Copy Cat 2.0.
