# The main part is in the top-right corner, This is a reaction between a glider#
# and a pi which results in nothing. However, if you remove one glider, the pi#
# creates a block. The next glider is destroyed if the block is there, so the #
# pi creates another block. But, if you remove another glider, the next pi #
# destroys the block instead. Next, I had to find a way to non-destructively #
# test for the block and coax out a glider. I used this reaction: #
# x = 8, y = 4, rule = LifeHistory: 2A3.A$2A3.3A$5.A.A$7.A! If there is a #
# block, , the Herschel disappears. However, without the block, the Herschel #
# emits a glider before being destroyed. he rest of the machinery - nearer the#
# middle - is used simply to get the glider stream out of the pattern.(It also #
# inverts the output, but that doesn't make much difference.) To try it out, #
# simply let the pattern run for a bit, then insert a block in marked ON state #
