Fractal visionaries and enthusiasts:

Today’s blast from the past is from way back — May 06, 1997.  But the image we see today is far different than the old one I posted almost 14 years ago.  I have reworked it to bring out the effect of translucency.

The formula behind the action is the MandNewt10, one in a series of formulas that I wrote many years ago and have since almost forgotten about.  I never did figure out exactly what they do.

I have dropped the rating system for the FOYD’s.  It’s hard to give proper ratings to images that are mere tweakings of earlier scenes.

The name “Emerald” is obviously based on the color scheme.

The calculation time of all these old images is quite brief.  After all, when I began the FOTD I was using a 100mhz-80486 machine.

To see the image without the need for calculation, check Hal’s web site at:

Paul’s site still has the old version posted.

My own FOTD web site is moving along.  The design is pretty well worked out.  In fact, the first month is almost ready.  We will upload it in a couple days and see how it flies.  I’ll post the address as soon as the first month is online and we see that it’s working.  If nothing goes wrong, there will be only 166 more months to get posted!

Thursday was quite chilly but sunny here at Fractal Central.  The temperature rose from a morning low of 14F -10C to an afternoon high of only freezing.  The fractal cats fully enjoyed the warm sun, but they would have preferred a bit less draft from the window.  The next FOYD will be posted in a couple days.  Until next time, take care, and I hear that the world is due to end on May 21.
