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