A new formula I've been spending too much time exploring

[simon.snake]

Hi Guys

I've been at it again with another new FractInt formula:

Code:

simon0047 {
  z = c = 0
  p = pixel:
  z = abs(z*z)-abs(p*p)
  c = c + 1
  c < 50
}

I used 150 maximum iterations, inside colouring set as numb with value 0 (it wasn't used by the formula), and outside colouring as tdis (which is total distance point travels).  I have set log palette option to either 0 or 1 with varying results.

The formula didn't bail out in the normal sense but iterated 50 times.

I've got a couple of colour maps which gave these results available here:

Now for the images, of which I've gone a bit mad:

One thing I have noticed is that you can only zoom in a handful of times before the image loses further detail (the effect looks quite nice but could be some bug within FractInt or my formula).

Hope you like it, and feel free to explore this formula yourselves and post your findings.
