#Life 1.05
#D Period 360 c/5 rake
#D
#D On the inspiration of a huge c/5 puffer construction by
#D Tim Coe, David Bell used spiders (c/5 spaceships that he
#D found a few months earlier) to bounce gliders back and
#D forth, leaving debris. Part of the mechanism involves 
#D Herschel reactions. In this version, the debris on the
#D left is cleaned up by extra spiders, and the debris on
#D the right is converted into a forward-swept wing of
#D gliders. Note that one of the spiders can be deleted to
#D leave gliders heading backward. Also, any of the eleven
#D circulating glider pairs may be deleted, increasing the
#D period to 3960.
