#Life 1.05
#D Still-Life Reflector
#D 
#D Converts one glider into 4 for any input stream
#D with a period of 672 or greater, unless pipelining
#D techniques are employed. It is a great challenge
#D to come up with the small, fast reflector that
#D consists solely of still-lifes. Dieter Leithner
#D (dietrich.deithner@dlr.de) is offering a $100
#D prize for the first stable glider reflector that
#D fits within a 50x50 box.
#D 
#D A glider collides with a boat in generation 97,
#D destroying the boat but creating a B-heptomino at
#D generation 107. This is converted into a Herschel
#D in 59 generations. Herschel conduits of lengths 64,
#D 77, 77, 64, 64, 77, 119, and 64 set the Herschel up
#D for a final collision to recreate the destroyed
#D boat.
#D 
#D The first stable glider reflectors were created by
#D Paul Callahan and Dean Hickerson in late 1996. This
#D one by Dave Buckingham, May 30, 1997.
