Pool Fun

Post by Tropylium » June 29th, 2013, 10:09 am

A fun and easy way to discover billiard table oscillators: fire up a Life variant supporting perma-on cells, draw an enclosure with them, maybe add some regular cells to induce asymmetry, and watch what happens inside. With some luck (and some familiarity with what billiard tables tend to look like to begin with), after a while some batch of chaos will settle into a pattern that also works in Life.

Starting with the stator of a known billiard table frequently turns out to quite easily generate it. Some other rotors frequently turn up elsewhere as well (cuphook, Gray counter, R2D2, burloaferimeter, and the 4-cell babbling brooks in particular).

For now, six discoveries in the p3 to p5 range I'm not seeing in the DRH collection (though some of them look deceivingly simple?):

Code: Select all

x = 83, y = 15, rule = B3/S23
