Ideally, it would be little modules that abut one another and
communicate neighbour cell state between modules somehow. Then add a
little logic behind each LED, and clock them in parallel.
ah, a CM-1 :-)
I liked the cm-1 but I would allow them all to have independent program
counters... :-)

MIMD rather than SIMD? The big advantage of SIMD is that you don't
need N copies of the instruction fetch and decode machinery....
The CA machine I'm thinking of wouldn't even have program counters;
each cell would conceptually be just a blob of combinatorial logic and
a flipflop for current cell state. There may be more state, such as
the 512 bits of RAM I mentioned in a past message, but that's an
implementation detail; conceptually those are control lines.
