Scrubber is a simple billiard table
A billiard table configuration
(or simply a billiard table
) is an oscillator
in which the rotor
is enclosed within the stator
. Typically the casing part of the stator is extended and several more or less trivial variations within it are possible (for example, the choice of induction coils
). Although billiard table configurations are considered interesting for their own sake, they are generally useless for creating larger patterns
because they do not expose any sparks
to interact with other oscillators or spaceships
It was long thought that it would be impossible to construct billiard tables by glider synthesis because the centers are not accessible from outside, but David Buckingham has succeeded in producing syntheses of some billiard tables.
Examples of billiard table configurations include airforce, cauldron, clock 2, Hertz oscillator, negentropy, pinwheel, pressure cooker, and scrubber.
