We used to have more java applets dedicated to fractals before we have made transition to HTML5 technology. Sadly we haven't yet updated some of them to HTML5. One of the best looking applets, Mandelbrot Set applet, is still among those to be "updated". So this time we suggest an interesting video about this fractal set by Numberphile.
