This demonstrates that several of the c/2 spaceships can be converted
to other ones using dominoes.  The top one converts a period 2 spaceship
into a period 4 spaceship and a block.  The bottom one converts a
period 2 spaceship into a period 6 rocket spaceship, and then converts
that into a period 12 spaceship.
