#C A period 128 rocket gun.
#C This uses a "nova" engine, which explodes to create four lobes of
#C temporary sparks.  One of the lobes dies naturally, and two of the
#C lobes are perturbed so as to re-ignite the nova.  The final lobe is   
#C perturbed into a period 40 spaceship.  This could be double-barrelled
#C if desired.  If one of the two p8 oscillators is removed, this becomes
#C a period 256 rocket gun.  If both of the p8 oscillators are removed,
#C this becomes a period 512 rocket gun.
#C David I. Bell, May 1997
