I thought that. But read their papers! I agree it seems unlikely.

Yep, I was only thinking about a discrete CA.

Yes, good stuff.

Hit submit at the top. It's not very clear.
Whoa! It seems gliders in a Penrose tiling are as common as dirt. :)Please let me know your name (is it Katsunobu Imai?) so I can giveyou proper credit.
Attached is a Ready file that implements the same CA.
Hi again,Recently Tsukamoto & Miyazaki reduced the number of states to 3.Because the construction is quite similar to the Goucher's glider, the samerule seems to be also effective in the case of kite & dart.

I prefer the gliders on the P3 tiling which trace out fractal Koch
curves, because there is provably no analogue in cellular automata
on periodic tessellations. I believe that my paper is published in
the Journal of Cellular Automata this month.
