Here is a test file often used to show off an open source clone of the print technology “Postscript”.

I wonder what the original origin of this illustration is. Others have, too: http://ptspts.blogspot.com/2010/12/dramatic-colored-picture-of-tigers-head.html
Maybe Minneapolis South High School was the original creator, and ghostscript picked it up from them? It is a mystery!
