Still lifes

Loaf

A seven-cell still life with a lopsided outline.

The loaf is a stable object with lower symmetry than the beehive. It is a good reminder that Life stability is local, not visual.

Measured on this board

No complete repeat observed yet. The detector compares up to 128 recent shapes.

Outside this finite board, cells are held dead. Reference facts describe the preset on an unbounded plane; measured repeats describe this board.

Share or embed this experiment

Create a paused copy of the current board, generation and speed. The link contains the cells; there is no account or server-side save.

What to watch

  • No phase change occurs after stepping.
  • The asymmetric shape is still perfectly balanced by neighbor counts.
  • It is common ash after messy reactions settle.

How to use it

Use it to contrast visual symmetry with rule-based stability.

Open the pattern in the lab, reduce the speed, and use single-step mode when a phase change is hard to see. The green preview marks births in the next generation; red outlines mark live cells that will die.
