Fractal visionaries:

I've got Fractint 19.6 up and running, and the good news is that it's a little faster, (on my machine at least), than 19.5.  I'm glad to see that the slow-down trend, which has been building since version 19.2, has been reversed.  In addition to the usual formula and parameter files, I've attached today's fractal as a parameter file with formula included for those running version 19.6.  If I've done my part right, simply snip it, save it as *.par, (* = any name you wish), and run it.

As for the picture itself, since yesterday's fractal had a demonic appearance and took 2 hours to draw, I felt it only proper that today's, which I have named "vision", should have a sacred appearance and draw in less than a minute. Actually it draws in 20 seconds.

I'm showing no favoritism in my choice of symbols.  I used the six-sided star because it gives such a symmetrical fractal.  Change p1 to 6, p3 to -4 and the symmetry to xaxis, and you'll get a five-sided star.  But the five-sided star is lopsided.

With this formula, p1 controls the number of lobes on the outer rim, p2, which must be kept small, controls the size of the inside star, and p3 controls the number of lobes on the inside star.
