Udonge + Tewi (2008-11-29)

Optical illusions.

Udonge and Tewi are PostScript programs that generate random optical
illusion patterns.  You will need a PostScript interpretor to run
them.  These commands usually works on Linux:


This will send the output to the attached printer.  Output is
formatted for letter-sized paper (8.5" x 11").

Using GhostScript, you can pass in a Seed argument to select a
specific pattern.  For example, to select pattern 9999 and write the
output to PDF files:

   gs -dSeed=9999 -sDEVICE=pdfwrite -dNOPAUSE -dBATCH \

   gs -dSeed=9999 -sDEVICE=pdfwrite -dNOPAUSE -dBATCH \

 - The output is semi-complex, and not all programs deal with it
   gracefully.  CorelDraw 11 will consume excessive CPU while parsing
   it, for example.

 - The output is semi-psychedelic, and not all humans deal with it
   gracefully.  But if you are already used to excessive moving
   bullets on screen, you shouldn't have problems staring at these
   patterns all day ^_^;
