nMuch simpler than von NeumannÕs
nModified a small component part of a previous automaton so that
it would reproduce itself
nA 10 x 10 loop with a 5 x 3 arm
nThe Òinstruction tapeÓ fits inside and extends arm by 6 units, turns left,
repeats this 3 times, till arm collides
with self, breaks off new loop and makes new arms
for each.
nReproduces in 151 time-steps
