Fractal Flame

0 gammas each channel on its own → pastel. 1 gammas luminance and scales channels together → saturated neon.

The log curve makes a pixel hit once nearly as bright as one hit ten times, which shows up as speckle wherever samples are thin. This fades pixels by d/(d+cut) in sample units; 0 is the plain formula.

Click the bar to add a stop, drag to move, select to recolour.

To cycle the palette over time, set Palette turns in the Animation section.

Select the F tab above to edit its affine and variations.

Turns rotates each transform's linear part, pulse breathes its scale, drift slides its origin, morph swings the variation weights and camera sways the view. Every channel runs a whole number of cycles per loop, so at the end of one loop the flame is exactly back where it started and a recorded clip repeats seamlessly.

Animating re-accumulates every frame against a decaying history — trail is how much survives each frame. Stopping bakes what you see into the flame and the still image's progressive refinement resumes.

The screensaver hides every control and runs the Animation settings above, replacing the flame every so often with a cross-fade rather than a cut.

With that off, the screensaver is a viewer rather than an editor: it cycles through mutations while it runs and hands your own flame back untouched when you leave it. Automatic entry is off by default for the same reason.

Budget is thousands of points per frame. The histogram is never cleared unless a parameter changes, so the image keeps refining for as long as you leave it.
