This pattern is a oscillator.
This pattern is periodic with period 2.
This pattern runs in standard life (b3s23).
The population fluctuates between 6 and 8.
This evolutionary sequence works in multiple rules, from b3as2ae3a through to b2-an34-w5678s01234-q5678.

(1) A collision between 2 Pi's, produced 2 beacons by gen.155, the first appearing at 151, very shortly after the forebears separated (149). The two beacons are not in phase, and mature by different evolutionary routes. Most elegant.

(2) The Beacon also lends itself to many decorations.
