Fractal visionaries:

Here's another fractal from one of my Mytest formulas.  I'm getting hung up on this series of formulas, which I wrote a while back and then forgot.  But there's no cause to worry, the formulas make good fractals.

Today's fractal is another quickie.  When I first saw it, I thought of a transparent stained glass window illuminated from behind by the last rays of the setting sun.

The appearance of depth and illumination from within is something I always strive for in my pictures.   Unfortunately, the effect is quite difficult to reproduce on a CMYK color printer.  The RGB of the screen just doesn't translate very well to CMYK.  The new 6-color and 7-color printers do somewhat better, but there's just no way that reflected light viewing will ever equal direct RGB viewing.  The cones of the eye are sensitive to red, green and blue, and you can't fight nature.  This is why fractals displayed as huge expensive transparencies look so impressive.

For tomorrow's fractal I haven't the slightest idea.  I'll just have to wait and see what's on the screen when the time comes.
