Drag point 'C' around, to 'paint' a picture of the mandelbrot set - black points are where the iteration is stable, dark blue where unstable. [br](It's a bit like doing a 'brass rubbing')[br]You can see the true picture by clicking 'Show Picture'

Simple exploration of the Mandelbrot Set (and the orbits of the iteration with different 'c' values).[br][br]This is the iteration: [math]z_{n+1} = z_{n}^{2}+c[/math][br][br]Try moving 'c' around to see the orbits change.[br][br]Stable orbits are coloured black. The colours 'outside' the set are determined by how quickly the iteration diverges...
