  1. #N Exponential aperiodic
  2. #C A p20 puffer moves east, sending gliders southwest.  Another glider
  3. #C bounces back and forth between the line of gliders and a stationary
  4. #C reflector (found by Mark Niemiec).  The round trip time of the
  5. #C bouncing glider triples each time, so cells along its path never
  6. #C become periodic; the intervals between successive passes of the
  7. #C glider grow exponentially.
  8. #C This is based on an earlier pattern in which a glider bounced
  9. #C between the outputs of two puffers; replacing one by a stationary
  10. #C reflector decreased the size of the pattern.
