#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.
