Fractal of the Day
by Jim Muth

|
Fractal visionaries and enthusiasts: Every time I take hope that the rush is near its end, another job turns up. An unusually busy day today left little time for exploring the world of fractals, so I had to make do with yesterday's leftovers. The result was better than might have been expected. If today's FOTD looks a bit familiar, it's not deja-vu. The familiarity can be explained by noting that today's FOTD is an outzoom and recoloring of yesterday's "Dingbats" image. But instead of dingbats, today's image reminds me of the eight tentacles of a giant squid. Yes, I realize that squid have those two long grabber arms in addition to the eight tentacles, but we'll ignore them for now, and stick with the name "Giant Squid". The rating of 6 might be a bit liberal for my usually conservative ratings, but it's a respectable image, one well worth a look. The image itself shows a typical midget that exists in a spiral. What makes this midget different is its mis-shapen West Bud, which has begun to split into two parts. (This splitting can be better seen in yesterday's "Dingbats" image.) With a running time of 6-1/2 minutes, the parameter file is somewhat slow. Relief is available however on Usenet at: The weather today here at Fractal Central was cloudy and damp, though no rain fell. The temperature of 65F (18C) would have been acceptable for the cats if they had been allowed outside unescorted. I'm sorry, philosophy fans, but I had no time to philosophize today. I'll try again tomorrow however. Surely, two days in a row can't be this busy. Until then, take care, and take it easy. Jim Muth jamth@mindspring.com |
