Polar Perspective 4

I really like the kinda tunnelish effects going on with this one.

It's dead simple too, three rules in the definition:

val polar4 = RuleBasedFractal("polar4",
  weight(2).color(ORANGE).colorWeight(0.3).rotate(72).invertRadius.scale(4),
  weight(3) color CREAM colorWeight 0.3 rotate 10 translate(5, 0) scale 0.9,
  weight(1).color(PURPLE).colorWeight(0.3).polar.scale(-2).translate(0, -1)
)
