I did some fractal zooms on the Mandel pattern. A composite image of
what one sees at FIFTEEN orders of magnitude is below.

ANGLE  PEAK MEM USED  TIME
1E+01  104367 bytes   1 sec
1E-01  104367 bytes   2 sec
1E-10  104367 bytes   2 sec
1E-13  104367 bytes   1 sec
1E-14  104367 bytes   1 sec

The Mandel code is cool because I can zoom across 15 orders of magnitude
with no real change in render time or memory usage, and only run into a
"pixelation wall" at the highest mag.
