Game of Life in Postscript
smashr writes "It never really occured to me that postscript could be used for something other than printing, until I came across this page. Evidently someone has written the classic 'Game of life' entirely in postscript. You can even send it to the printer and have it output every single iteration.. now that would be a fun prank."
Sad memories of being a nine year old loser are flooding my brain at the mere mention of "The Game of Life".
Ok, someone write an OS in it.
I wrote a program that substitutes occurances of one string with another one. You send it to the printer than laugh as everyone else's pages mysteriously have the word "this" replaced with "that". One time I loaded it on just before a friend printed his source code. He couldn't figure out for the life of him where his semicolons had gone! Ah... youth.
The best part is, the code stays resident until the printer is power cycled. This enables slightly more sinster uses for this sort of thing. One of my professors used to joke about using as program like this to change the numbers on his paycheck when it was being printed!
The code is still on my website near the bottom. It's called PSReplace.
