- Scale
- Size of one cell, and with it how many the board holds.
- Density
- How much of the board starts alive. Life is fussy about this — too sparse and it barely catches, too crowded and most of it dies in the first few generations.
- Revive
- How often the picture strikes a fresh live cell. At zero the board plays out and settles into still lifes and blinkers; above it something is always starting.
- Trail
- How long a cell stays visible after it dies, which is what turns a flickering board into something with movement in it.
- Tint
- Colour of a living cell. The trail sits a little further round the wheel.
- Glow
- Extra light thrown by living cells.
- Blend
- Weight of the board over the picture underneath.
- Speed
- Rate of the effect motion. Centre is the authored speed, hard left a tenth of it.
