Fractal of the Day

Fractal visionaries and enthusiasts: Due to the continuing task of preparing to move, there will be no FOTD for February 26 or 27. The next FOTD will appear on February 28. Today's image is a view in the Oblate direction of the curious rectangle located at Z coordinates 0.00019+0.07388i in the C=(-1.7435) Julia set of the Z^(2.003)+C Mandeloid. As is immediately obvious, the rectangle, which is at the center of the image, remains a rectangle in this new direction, even though a good bit of stretching and skewing was necessary to make a proper rectangle of it. I guess I could have given the image a name and rating, but it is the kind of fractal that, for those with ears to hear, speaks for itself and needs no words or numbers. The render time of 5 minutes is not too bad. Downloading the completed GIF image from the FOTD web site at: Too much wind and a temperature of 39F 4C kept the fractal cats safely inside here at Old Fractal Central on Friday. The work kept me equally subdued. Due to the continuing rush, the next FOTD will be delayed until February 28. Until then, take care, and look for light.
