Generating Your Own Fractal Pictures (JAVA can be slow!)
For best results, select: xc around 33, yc around 51, xf around 15.

The model: Z(n+1) = Z(N)*Z(n)+Zc; Z=X+iY
Zc= Xc +iYc (for Juliaing Set); Zc=X(0)+iY(0) (for Mandelbrot Set)
Z(0)=X(0)+iY(0)=(X0+c*Xf*IX) + i(Y0+c*Xf*IY); (IX,IY) are the index of pixel.
Xf : The magnification factor (Zoom in with bigger Xf)
