Crystal Growth 2

From Softology's collection · B1,3/S1-2/C5

A crystal from one cell whose inside never stops flickering.

Crystal Growth 2 in the 3D Game of Life: cells as cubes in a 15×15×15 box, 40 generations in.
After 40 generations from a single live cell in the centre of the box, in a 15×15×15 box that wraps at its edges: 864 live cells.

How the rule works

Picking it in the app restarts the world from a single live cell in the centre of the box.
