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:

x_{n + 1} = y_{n} -
sg(x_{n})*sqrt|b*x_{n} - c|

y_{n + 1}
= a - x_{n}

y

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.
