It's hard to find areas that aren't pretty!

I have some suggestions for you, however.  Don't just request coordinates,
request the coloring scheme, too.  One person's beautiful area may be
drab if you colored it differently than he did.  If the contents of the
color luts were available, you could reproduce somebody else's effort
exactly.

You've probably already discovered that a versatile pseudo-coloring
program is vital.  By playing around with the LUTs you can turn any
single image into dozens of different pictures, all gorgeous.

Another hint - be sure to use histogram equalization when converting
iteration values to pixel values. (Attempting to put the same number
of pixels in each bin from 0 to 255)  To my eye, it results in much
more pleasing images.
