Fractal visionaries and enthusiasts:

Today's image reminds me of a reservoir of hot magma lurking just beneath the earth's crust, which is why I named it "Boiling Magma".  Actually, magma doesn't boil until it reaches the surface and becomes lava, but we'll ignore that small detail.

If the image seems a bit familiar, there's a good reason.  It's a blow-up of a section of yesterday's Seahorse Valley image, with only a bit of skewing and a small tweaking of a few color registers.

The rating of a 7 seems to be about what the image is worth.  And the calculation time of 3-1/4 minutes is also a good value.

A mix of clouds and sun with a temperature of 86F 30C made Tuesday a rather warm but pleasant day here at Fractal Central.  The fractal cats, who never get to go outside, had a brief thrill when a roaming tomcat passed through the yard, leaving his scent behind as a calling card.

My day was busier than average, but not excessively so.  The next FOTD will be posted in 24 hours.  Until then, take care, and believe it only if it's true.
