This page is dedicated to fractals generated by PostScript programs. PostScript is a powerful language used in printers. The hole ide with this page is to collect PostScript programs that generate fractals useing a postscript engine either in a printer or in a PostScript viewer. If you have or know about other PostScript fractals please send me an e-mail.
This fern was posted on news by Maurizio Loreti <loreti@pd.infn.it> when I did request PostScript fractal resources.

When I did try to learn PostScript I wrote a postscript program that use recursion to draw a tree.
"F. J. D. Uhlik" <uhlik@sals.icpf.cas.cz> did post this tree on Usenet
This snowflak is distributed as an example with the ghostscript program.
John B. Oxton <joxton@icds5.rsc.raytheon.com> did copy this fractal from the net years ago.
Joseph Hertzlinger <jhertzli@ix.netcom.com> did post a Korck Snowflake on Usenet and hi improved it with filling the snowflake with gray color.
Joseph Hertzlinger <jhertzli@ix.netcom.com> did write this Appolonian net ps program.
John Holder <jholder@frii.com> did provide this fractal in response to a news posting.
