AUTOMATON*
Tron
A two state automaton using the Margolus neighbourhood. As with 'Critter',
most cells reverse their state at each generation, producing a flashing
display; careful choice of colours prevents this from being too garish. Try
200x100 & 100x50 windows. Tron is a reversible self inverse automaton -
altering phase at any stage, then resuming, causes the automaton to undo
it's previous behaviour.
