#C Three related c/3 frothing spaceships.
#C These have periods 21, 12, and 6.  The original period 21 frothing
#C spaceship was found by Paul Tooke.  The smaller version shown here is
#C by Stephen Silver.  The spaceships can be changed from one form to
#C another using glider impacts into the back end of the spaceship.
#C Most of these conversions use a symmetrical pair of forward gliders.
#C These spaceships are very useful for period multiplication of c/3
#C rakes since they change forms so easily and are relatively robust.
#C David I. Bell, October 2002
