#Life 1.05
#D Crystal&decay 2700
#D
#D A p150 gun fires at a pair of pentadecathlons. When the first glider
#D hits the PDs, it is reflected back and hits the second, forming a
#D honey farm. Subsequent gliders form a crystal growing upstream. When
#D the crystal reaches an eater near the gun, it begins to decay.
#D When it's all gone, the cycle begins again.
#D
#D The period of this pattern is 2700, but by moving the PDs, any period
#D of the form 750 + 1950n (n>=0) can be obtained.
