One thing I have noticed when Jim uses his popular MandelbrotMix4a formula is his use of almost exclusively C or 1/C as the constant. Some time ago I was experimenting with that formula using other functions of C for the constant. Using tan(C), I stumbled onto this fractal which gave me the impression of looking through a rusty port hole of a sunken ship at some scallops in clear blue water. I'm sure Jim would certainly have found a better color palette to improve its rating but I like it as is. I wish Jim a nice vacation.
