Fractal fan

A cross-section of a fractal brush was drawn out into horizontal lines and three red lines were added. 'Polar coordinate' from the 'distort' menu turned it into an oval. This was placed over a white background., merged down. A quarter was then 'inverted' changing the white to black and the red to cyan. This repeated in the diagonally opposite quadrant. The whole layer was then copied. The top layer was 'skewed', taking one corner over to the opposite corner and vice versa. I think that that was repeated.
