This is the original fractal (which I thought resembled a Christmas tree).  The other images that follow are modified versions of this one.  If you would like any (or all) of these to use as a background on your computer, I'd be glad to send you a full-size version (just let me know what your screen resolution is set to). Also, different colors and textures are possible for many of these, if you have other preferences.

By the way, here's a link to a few examples of some pretty cool fractals.
