I needed these for a scene, extracted the method from John VanSickle's 
1999 IRTC Entry, "Boxer Solves A Problem"

http://www.irtc.org/anims/1999-07-15.html

and modified it slightly to produce both types of Penrose Tiles (see PB-SF)

(Again:  All credit to John for what works in the "include;" any blame 
on me for what doesn't.)

First Pic "Type A"  "Kites and Darts"
Second Pic "Type B" "Rhombs"

p.s.  Any suggetions for a decent JPEG compressor (free) for Windows? 
I'm using Serif Software's "PhotoPlus 5.5"  It's free, but it's 
inefficient and poor quality.  These images should run about 25k for the 
quality of output.  For my Mac (at home) I have Photoshop with some 
plug-in (can't remember what) that improves Photoshop's compressor 
considerably.

Of course. . . . How obvious. . . (I'll have to remember that.)  ;-)

LOL  But, of course, now we know what they're really shaped like.
