A 4000 element Mandlebrot texturing technique that sweeps away the
extreme thirds of a finite space [0,1].
There is no user interaction.
To construct a Mandlebrot trema generator, imagine a space that
is uniformly distributed over an initial domain [0,1]. Define this
space as an object. Divide this object into three equal sections
[0,1/3,2/3,1] and cut out the middle third. Represent the area cut
as a sphere of blackness. Repeat the process for the remaining two
thirds (one lower and one upper).
