How it works

a b c d
The four constants of the de Jong system. Small changes reshape the whole figure — that's the chaos.
Iterations
How many points are plotted. More points = denser, smoother image.
Brightness
Overall glow of the plotted lines.
Gamma
Contrast curve — low lifts faint detail, high deepens shadows.
Diffusion
Softens each point with a little spread, for a hazier, painterly look.
Axis
How the maths maps to the screen. Mirror doubles the figure symmetrically.
Mapping
How density becomes brightness — Linear is balanced, Raw is punchy, Equalized reveals faint structure.
Color
Two colors blended across density, or one single color. Swap or randomize.
