This applet draws a coloured Mandelbrot set.
[color=#c51414]WARNING[/color] The applet computes the colour of 102400 points using 20 levels of colour so it needs a long time to complete the task (about an hour on an Intel Core I7, 2 GHz), but the game is worth the candle. For a faster rendition without color look for my [i]The Mandelbrot set[/i].
