Type any iteration formula and see its escape-time fractal. Drag to zoom into a rectangle, scroll to zoom at the cursor, click to re-center.

Preset Iteration z ↦ f(z, c) Start value z₀ (may use c)

z = current value, c = pixel position. Operators: + - * / ^; implicit multiplication works (2z, 3i, c(z+1)).
Constants: i pi e
