The new release 2.50 of the free JWildfire-software now supports also the Leap Motion Controller for animating fractals.
There is a new tab to control which motion-property should affect which fractal-property. You can then view the result in realtime and also record it.
After recording the motion is stored as a set of motion-curves bound to the fractal. This animated fractals can then be rendered in order to generate animations of high quality.
If your fractal is 2D you can even use Chaotica to render it (produces very nice results in less time).
