FOTD -- June 21, 2001 (Rating 5) Fractal visionaries and enthusiasts: What do you get when you mix some Z^(1.1) with some Z^(-1.1)? A pit of boiling hot lava of course. I named the image "Beware the Lava Pit". Actually, I should have named it "Beware the Magma Pit" since the scene is underground, and molten rock is known as magma until it reaches the surface. Only then is it called lava. When the time came to rate the image, I studied it several minutes before realizing that it was merely an average image. The rating of 5 is average. There's nothing wrong with being average, it's just that I like my FOTD images to be above average, and the greater the number of above-average images I post, the higher the standard of average becomes. One thing that does not change however is the average render time of my FOTD's, which currently stands around 12 minutes on my tired, worn-out P200 machine with the exhaust fan that needs to be nudged before it starts turning. When I forget to nudge it, the smell of the over-heated power-supply unit soon reminds me to give it its nudge. Today's image requires 25 minutes to complete on my machine. It will finish faster on faster machines. But the fastest way of all to see the lava pit is to download the completed GIF image from one of the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Heavy rain fell during the day Friday here at Fractal Central. The cats, who were confined to the indoors, turned sullen in the afternoon. Several treats of tuna were needed to restore their spirits. Today is starting with a bit of sun, but heavy storms, and perhaps hail, are due this afternoon. I doubt that the cats will have a good day. If the grass dries enough, I'll trim it today. If not, I'll let it grow another couple inches. In any case, I'll visit Fractal Land to track down the next fractal. Until next time, take care, and beware.
