This is Fleximal - an unknown animal with a rule30 pattern on its skin. I made it to play around with cellular automata. A fast computer is of advantage to render. To add the pattern to the aninal took 44min on my 3.5Mhz PC. The rules of the cellular automation patterns ar simple, but an implementation with OpenSCAD took my old brain a while -- uaaah recursions!

I failed to add the pattern to the fleximal directly. So there is one openscad file to create the animal, one to create the pattern and one to add the pattern to the animal. Every newly rendered pattern looks a bit different, because of the first random line.

Happy printing!
