Follow the sequence of cardioids above the period three bud up
and to the left.  The sequence leads to a pre-periodic point in
a spiral path.

I have posted 02281554.gif to alt.binaries.pictures.fractals, a
picture of the period 32 Mandelbrotie which is about 10^(-30) long.
The sequence is (for those who might wish to explore)

In this picture the filements are relatively very long, going out
in slowly curving spirals.

Each filement has n=p-3 barbs on it where n is the number of
Mandelbroties in the sequence.  This is because to get to this point,
we went past n branch points like the first one (branching to the right
ending at +i).

Make that Poul Anderson.
