A period 3960 c/5 puffer.
This puffer is constructed from 12 c/5 "spider" spaceships and a pair
of gliders.  The first glider is turned into a block by a spider.
The block is hit by the second glider to create a "slow death" pattern.
Further spiders perturb the slow death to create a Herschel plus some
junk.  The Herschel emits its normal glider, and a perturbation of the
Herschel creates a second glider.  These two gliders then repeat the
whole reaction on the second side of the puffer.  Adding pairs of
gliders into the loop can reduce the period.  The reaction shown here
is the basis of the first clean c/5 rakes.
David I. Bell, September 1997
