#C Jagged lines
#C Jagged lines of gliders, formed by a drifting collision of two LWSS
#C streams, crash to form an approximately vertical jagged line of pairs
#C of blocks.  I don't know if the line stays within a bounded distance
#C of the center line, or extends infinitely far to the left, or to the
#C right, or both.

Here's a GIF file generated by a Mathematica program that simulates the
key features of the pattern.  It shows the locations of the first
11,426,769 block pairs, in generation 4,113,636,213.  The picture has
been stretched horizontally by a factor of 488; the actual width of the
jagged line is 140,480 cells and its actual height is 685,605,960 cells.
