Fractal visionaries:

Last evening, I promised an IF-ELSE fractal for today, and I've found one worth sharing.  My own first efforts at IF-ELSE formula writing have failed to find anything of interest, so I took a formula posted a few days ago by Ron Barnett, added a few variable parameters to it, and set it loose.

It didn't let me down.  This formula has no end of great fractals in it.  Today's picture is just one of a dozen or so equally striking ones this formula has produced.  The coloring is in my preferred style of looking toward the source of light.  I hope you enjoy it.

In a month or so, I'll start shopping for a new computer to replace my poor old overworked 486.  Before I buy, I plan on doing a speed test, by running the same test fractal on different machines.

I also hear various rumors I'd like to check.  I've heard it claimed that the MMX technology sacrifices accuracy for speed, and that its fractal performance is therefore compromised.  I've also heard that the Pentium Pro, (40686), is optimized for 32-bit apps.  I'm curious to see if this affects its fractal performance.  The new Pentium II processors appear interesting.  I'm curious to see how they compare with the Pentium Pro.

Well, while I'm dreaming of my new computer, I'd better send this off before my mail server goes down again.
