Quadrup Two 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 basically just replaces the formulas with these:

xn + 1 = yn - sgn(xn) * sin(ln|b * xn - c|) * atan(|c * xn - b|2)
yn + 1 = a - xn

In this fractal, a, b and c are constants which, by default are initialised to 34, 1 and 5 respectively, although these can be changed with <param> tags.
