Hopalong Orbit Fractal

If your browser supported Java, You would see a nice fractal here.

This fractal's applet is just an extension of gingerbread's applet. It was originally discovered by Barry Martin of Aston University. It basically just replaces the formulas with these:

xn + 1 = yn - sg(xn)*sqrt|b*xn - c|
yn + 1 = a - xn

In this fractal, a, b and c are constants which, by default are initialised to -55, -1 and -42 respectively, although these can be changed with <param> tags.
