I like the idea! Well executed, too; zooming into the Julia as the changes of the invariant C get ever smaller ensures there is always significant change in the Julia set.

Note that the speed of Mandelbrot set zoom is 2x faster.

The "factor of 2" for z^2 (and n for z^n) compression of Julias isn't just the zoom it is also the required precision.
