The final prove that there are errors in the fractal calculation:

The fractal has no rotation. Only a simple translation from outside into the
fractal. As soon as you come near the shape of the fractal, you have a
calculation change of the fractal. In the animation, you can see two
different ellipses which grow. Inside the ellipses you can see, that some
parts of the fractal are on another position as they were at the begining
(Outside the shape). The amount of ellipses varies on the angel you hit the
shape. When the fractal slowly rotates around the y-axis you can see up to 6
different ellipses they start from a point and grows over the whole
fractal-image.

Can anyone explain this kind of animation effect?
Is that also a Wheel effect??
