Program for Rendering stacks of julias

[slinker]

I am making fractal columns by generating stack of julia's that are successively calculated along a curve on the mandelbrot set.

As an example, I might have a trajectory from -.1+0.8i to .4+.4i taken in equal steps of 100.  For each step, I calculate an image of the julia set for that complex pair.  Then I select a threshold boundary for the images to make them bitonal. Then I stack the images in 3d and if done right, makes a pretty 3d solid.

I am creating the images with messy python script. 

Is there way to do this in mandelbuld3d or other software that I can see a 3d rendering as I change the trajectory and threshold? 

If anyone knows how I'd love to know.

Thanks in advance!
