This sounds like great fun! What program was it?
(Hmm, might be a fun java applet for a transhuman website, a sketch of
possible future developments. Now link it to the Foresight
Exchange...)

Fun. Aesthethics. I like CAs :-)

It would likely be significantly faster and denser than the chips. And
if we could tune the transition rules, then we could get lattice gas
dynamics with a wonderful resolution, or make universal computations
for real. Or just run the greatest Game of Life ever.

I think so. Normally the units form a cylinder, with a helical tiling
of the subunits (and some interesting stability properties; they are
dynamical structures, constantly being formed and dissolved at the
ends). The fun thing is that it is possible that the units flip
around, acting as a cellular automaton which can have all sorts of
dynamics. If this is used for the transport proteins (dyneins and
kinesines) that move vesicles along the microtubule is anybody's
guess. I really understand why some think microtubulu are "magical",
they are extremely subtle self-organized structures.

What about using reaction-diffusion dynamics to create complex local
strucures? That might be useful to maximizing catalytic efficiency,
adapting to changes in the environment or changing color.
