Here's the 3D version of Miller and Fredkin's Salt CA, running in Ready. With an 8-cell strand as shown, it traces out (if you track the average location) an approximate circle. The surprising thing about this rule is that with more cells this approximation gets better and better!

Cool stuff. I've played with it a bit at http://busyboxes.org, and noticed that some behavior is very similar to the 2d "Critters" rule (which uses Margolus). Specifically, "delayed release", "harmonic chaos", and string-like vibrating objects in general.

+Ivan Zvolsky: yes, good point. I wonder if there's a 3D version of Critters that would also exhibit circular motion.

Hello. Seems it is reversible CA? "Reversible Ants" CA I mentioned earlier might have simple 3D extension with interesting behavior. I installed Ready (on XP!) but do not know how to implement what. Recently I also found that Ants are universal http://quantumbot.wordpress.com/2013/07/27/reversible-anto-logic/

Hi Alexander. Yes, it's reversible. You can download the Salt CA for Ready here:
https://reaction-diffusion.googlecode.com/svn-history/r1156/trunk/Ready/Patterns/Salt/salt2D_demo.vti
https://reaction-diffusion.googlecode.com/svn-history/r1156/trunk/Ready/Patterns/Salt/salt3D_circular330.vti I'll make a new version soon that includes these files.

Thanx, it works even on my computer , unlike Google+. Yet I may not guess, how to implement "ants" despite quite simple rules acceptable both in 2D and  3D case

Just checked Ants in 3D with Delphi  POV Ray http://ayvlasov.wordpress.com/2013/07/31/flying-bricks-ca/
