Extremely impressive is a period-6 oscillator that was found in August 1976 by David Buckingham.[1] A variant of this oscillator with a slightly larger stator can be synthesized from 29 gliders.[2]

Despite the initial appearence of the oscillator, it is in fact not a billiard table configuration - a "wall" that appears to be a part of the stator is briefly broken and immediately repaired over its course.
