Simulating Billiard Balls in Other Models of Computation
It is possible to simulate billiard-ball computers on several types of reversible cellular automaton, including block cellular automata and second-order cellular automata. In these simulations, the balls are only allowed to move at a constant speed in an axis-parallel direction, assumptions that in any case were already present in the use of the billiard ball model to simulate logic circuits. Both the balls and the buffers are simulated by certain patterns of live cells, and the field across which the balls move is simulated by regions of dead cells, in these cellular automaton simulations.
Logic gates based on billiard-ball computer designs have also been made to operate using live soldier crabs of the species Mictyris guinotae in place of the billiard balls.

Famous quotes containing the words simulating, balls, models and/or computation:
“Would it be possible to stand still on one spot more majestically—while simulating a triumphant march forward—than it is done by the two English Houses of Parliament?”
—Alexander Herzen (1812–1870)
“I count those feathered balls of soot
The moor-hen guides upon the stream,
To silence the envy in my thought;
And turn towards my chamber, caught
In the cold snows of a dream.”
—William Butler Yeats (1865–1939)
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
“I suppose that Paderewski can play superbly, if not quite at his best, while his thoughts wander to the other end of the world, or possibly busy themselves with a computation of the receipts as he gazes out across the auditorium. I know a great actor, a master technician, can let his thoughts play truant from the scene ...”
—Minnie Maddern Fiske (1865–1932)
