Here's a video of the Game of Life on a Penrose

I love that oscillator down in the bottom right!

The challenging part is deciding what constitutes the 2d map in a
non periodic tiling.

Isn't it just a graph?

It would be the tiling, right?Am I missing something?

You don't need a 2d map. You define the behavior of the cell in
terms of the states of its neighbors.

Once I seriously wanted to have Penrose Tiling tiles in my bathroom
but after soon found out nobody manufactures such tiles and would
have to produce them manually with a tile cutter.

The CS building in Carleton College has them in the lobby:http://

Waterjet cut them from a bigger slab.

Wouldn't this leave sharp-ish edges?

Sand 'em down?

That's probably not great for flooring, but might be fine for
walls or a backsplash.You might be able to relieve the edges
by tumbling, but at the cost of changing the surface finish.

Not Penrose tilings, but my math professor's bathroom floors are
pretty cool https://www.math.ucdavis.edu/~greg/floors.html

You could buy mosaic tiles in the forms (they exist), and put
those then together.

That's not a Penrose tiling. The pieces are the wrong shape.

Also not the math dept's bathroom, it's a faculty member's
personal bathroom floor.

Would probably be easier to rent or buy a kiln and then make your
own ceramic tiles. Cutting them after the fact is a frustrating
experience.

You'd want a slab roller too so as to get consistent thickness,
unless you want a hand-made look.

Anybody got a link to a working example?I mean, this seems
straightforward enoughThis is sorta my field. My goal is pretty
pictures. Would this make pretty pictures? I dunno.ok, here's a
