[Fractint] Interchange

26 Nov 2012

      This fractal reminds me of an interstate highway interchange. I will be
working on some user interface enhancements for Fracton so I probably won't
post many fractals until it is done.

Here is a link to an image:

The Fractint compatible PAR file for the image is:
