The following images are "fractal" images generated on Departmental machines.
They are portions of the Mandelbrot and Julia sets (plus a few others). These
sets are generated by taking a complex polynomial f(z) and applying it to
itself repeatedly for different values of z.   The polynomial may become
essentially infinite after say n(z) iterations.   The images are produced by
assigning one colour value to each possible value of n(z) (modulo 256) and 
plotting it for different values of z = p + iq..  The real axis is plotted
horizontally and the imaginary axis vertically (usual Argand diagram convention).

Each image is displayed along with a brief description and the minimum and
maximum values of p and q.
