A c/3 period 45 backwards MWSS rake.
This produces a backwards travelling MWSS every 45 generations.
It is composed of a period 45 spaceship which produces a cloud of smoke
every 45 generations, a period 3 edge-spark spaceship which perturbs the
smoke into pre-blocks, and a period 45 forwards rake, whose gliders impact
on the pre-blocks to form the MWSS's.
David I. Bell, April 1997
