! "blinkership" (cells 72 length 17 width 30 generation 0)
! This is a puffer train which leaves no permanent exhaust, and yet grows
! arbitrarily large.  The engine and spaceships to the right of the blinker
! produce a new blinker every 12 generations.  Without the object to the left
! of the blinker (a predecessor to traffic lights), this puffer train would
! just leave behind an infinite line of blinkers.  However, the object reacts
! with the blinkers with a period of 26, and totally destroys them.  The speed
! of the reaction is 6/13 the speed of light, which is slightly slower than the
! rest of the spaceship.  Therefore, every 156 generations the puffer train
! grows in size by one blinker.
