I did this in the gnuemacs lisp a while back, and decided I wanted it 
faster... Feed it a textfile in a (large=fullscreen) CLI window.
The code is real simple.. It takes incoming text, assigns each letter
a unique position, and then scrambles the letters. After that find the
position assigned to the letters, and put them on the screen.
This gives the display that "randomized" look, yet no position is written 
twice. No restrictions on this piece of code... It could be fun to use
for small texts to be displayed in programs, etc..
