it's quite easy to program such a thing. below is python code which
permutes a simple ascii picture and asks the user to find out the 
original picture. it's not hard to modify the program such that it
permutes a text file containing some ascii-art - if you are interested,
please mail me.

	have fun!

ps: python can be obtained from www.python.org. its easy to install
(interpreters exist for various platforms) and a very good language for
this kind of stuff.
