#B gosper
#C The classic period-30 glider gun by William R. Gosper. 
#C This is made of two of a pattern
#C know as the "queen bee", which
#C sometimes occurs naturally,
#C whose debris can be deleted on 
#C the sides by blocks or eaters.
#C But a collision in the center
#C can, as seen here, miraculously 
#C form a glider. Just one of these
#C moving back and forth is called
#C piston (see the p30 in OSCSPN2).

#C p120: A foursome of Gosper guns that emits gliders with period 120
#C An interesting detail of the p120 is that it operates by repeated
#C creation and destruction of an eater at one of the glider stream
#C intersections.
