> each of which moves at a twelfth of the speed of light

I presume this is cellular-automata jargon for moving one cell per cycle?

edit: btw, I just saw the discussion about not posting to HN yet on the boards. My apologies, had I seen it I would have waited. I only posted this because (to my surprise) it looked like nobody else had and GoL posts are usually pretty popular around here.

Yup, the "c" in spaceship speeds, like "(2,1)c/6", is the same c as in "E=mc^2". It's a good analogy -- one cell per cycle is the maximum possible speed that information can travel in the Life universe.
