Hello everybody,

Has anyone ever made a code for generating a surface with penrose tiles (two
rhombi, all sides equal, one with an angle of 36 degrees and one with an
angle of 72 degrees, allowing to fill a surface).


Greetings, Erick

There is, at least, someone who did this, look at the "Great 
Engineering Achievements" IRTC round, the image is named
"25_04.jpg"

Yes.  Although it is not painfully obvious, my IRTC entry "Boxer Solves a
Problem," which was my July 1999 entry, opens with a bugbot crawling over
a penrose pattern.  The source is included.  You can find links at:

Check out the penrose tiling include file at:

Oh dear, this page contained _lots_ of eye-candy! Too bad it's all in
Japanese (The English version is not at all completed...)

You can still download the source from:
http://www.interq.or.jp/blue/kawashu/include/i05.html

Look for penrose.txt for the include file and pensample.txt for an
example of the usage. There are other downloads near the bottom of
the page but I have no idea what they are...?

My God, John, I feel so stupid. Last week, I browsed through the IRTC files
(on the cd, supporting the good cause!) and I didn't notice your wonderful
animation.

Thanks everybody for the handy tips. The Japanese page looks good (though I
too have some trouble understanding the lingo).

Meanwhile, I spent too many hours calculting vectors and rotations and
putting the tiles one by one  in a frame.
