Brian’s Brain

A three-state automaton that can never hold still — every firing cell has to spend a generation refractory, so the board is permanently full of travelling wavefronts.

Runs live on video, images, a camera or generated art. Stack it with any other effect, and route LFOs, envelopes or any of ten audio bands to its controls so it moves with the music.

Controls

Scale
Size of one cell.
Density
How much of the board starts firing.
Revive
How often the picture fires a fresh cell. This rule sustains itself, so unlike Life this is here to keep tying the board to the clip rather than to keep it alive.
Afterglow
How visible the spent cells are behind a wavefront. They are what make the fronts read as travelling in a direction rather than as flickering.
Tint
Colour of a firing cell.
Glow
Extra light thrown by the firing front.
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.
