Hover over the Mandelbrot set to see its Julia set live. Click to lock.
The Mandelbrot set is the set of c ∈ ℂ for which z→z²+c remains bounded. Each point on its boundary generates a distinct Julia set J(c).
At c=0 the Julia set is a circle; near the boundary it becomes fractal dust.
Scroll to zoom on the Mandelbrot panel. Click to lock/unlock the Julia set.
