Mandelbrot coral

[Temoto-kun]

Hey guys, I discovered some interesting pattern using the Mandelbrot set.

More details in the attached zip file. It has two .rle patterns.

The symmetry axis you noticed in these patterns is quite common in coral's kind of rule.
Every symmetric starting seed generates a symmetric pattern.
For example:

Code: Select all

x = 8, y = 7, rule = B3/S45678
2b3o$2b3o$2b3o$8o$2b3o$2b3o$2b3o!

Code: Select all

x = 16, y = 16, rule = B3/S45678
15bo$15bo$15bo$14b2o$14b2o$14b2o$14b2o$14b2o$14b2o$14b2o$14b2o$14b2o$
14b2o$14b2o$3b13o$16o!

Is there at least some basis pattern for, if not all, the majority of corals?

I'm not sure what you're asking here… but while I have not seen much in-detail study of Coral, I would not be surprized if the growth could be largely broken down to a number of recurring growth shapes. After all, the activ region is quite thin and split to separate areas, it should not be able to support as much pseudo-randomness generation as an entirely chaotic rule. Still the feedback from flake edges laid before might suffice to keep variation going for a long while.
