An example of unbounded growth in rule 110. The initial condition consists of a block of length 41 inserted between blocks of the background. New structures on both left and right are produced every 77 steps; the central structure moves 20 cells to the left during each cycle so that the structures on the left are separated by 37 steps while those on the right are separated by 107 steps.
