Penrose Tile generator Does anyone know if there's a client or web app that generates Penrose patterns which can then be converted to a tileable rectangular background image for web site?
I found this http://stephencollins.net/penrose but I can't seem to get a rectangular shape out of it for web use. Thanks.
 A: I believe, since Penrose tilings are aperiodic (lacking translational symmetry), there isn't such a rectangular shape.
A: I found this java software that exports as PNG. 
You cannot tile it, just use an image.
A: Only dragging up an old post because there's still something more to do -- if you want a penrose tiling as a background, I built one a while ago that will generate an image for your purpose:

Of course the tiles don't fit perfectly into a rectangle (they are clipped at the edges), it should work just fine as a pretty background image. 
A: here is a shadertoy program for 5 axis quasi symmetry pics, it's not as tileable as a tile version.
I just wrote a program to investigate 5 fold symmetry in 2d, it generates something akin to penrose tiling.
here is a pic 

and a video on YT:
i am not convinced that it can't practically be tiled in a square shape, you may have places where only one triangle is wrong in a frame of 1000 of them or something, else you could find a place with good 4 fold symmetry and blur some small places where is different on the edge.
A: I found this page, it generates an SVG image: https://craftdesignonline.com/penrose/
