Reflections in an Oil Slick

FractInt formula I created.  Using inside colouring set to bof60 creates these beautiful patterns.

Formula is:

Code:

simon0064-A {
  p = pixel
  r = real(p)
  i = imag(p)
  m = (flip(maxit)+maxit) * p
  x = sin(r * r * r) / p2
  y = cos(i * i * i) / p2
  z = flip(p2 * p)
  c = |m|:
  x = cos(p + x) * cos(p + x)
  y = sin(p + y) * tan(p + y)
  z = z * z + p * (x + flip(y))
  c = c - 1
  c > 0
}

Feel free to have a play with this formula yourselves.
