Fractal
visionaries
and enthusiasts:
Today's search takes us to a Julia set 80 levels up the logarithmic
hyperspiral of the Z^(sqrt(2))+C Julibrot. The image we find
there is a rather delicate network of finely-divided 'outside' stuff.
I gave the image no name, though I did give it a rating. IMO, the
image rates a 7. The render time of under 2 minutes is brief
enough so that no one should be afflicted with impatience while
rendering it.
About one foot, or 30cm, of snow fell Saturday night here at Fractal
Central. The fractal cats sneaked onto the porch this afternoon
and checked the conditions for about one minute before determining that
the day would be better spent indoors. My day was spent clearing
snow and drinking coffee. The next FOTD will appear in 24
hours. Until then, take care, and what's it all about?
