Just a quick test of Jesses latest update of the wonderful Mandelbulb 3D [link] it is now possible to see the inside of all fractal wonderlands. I see so many shapes to zoom in on... but damn, is it hard to navigate. 
I just had to share this raw test, now the infinite infinite number of possible images has doubled.
This is the inside of a plain negative scale amazing box. -no rotations or anything else added...
Mandelbulb 3D ...did I mention that already?
Time to go inside fellow 'bulbers' !

This is quite something for "just a test"!
In short: check the "Inside rendering" box in the formula window.
Thank you very much Leonie!
Glad you got it to work!
OK, you enable it on the formula tab AND the on the gradient section? I seem to be able to render ONLY the inside or ONLY the outside - not both at the same time. What's the method?
THANKS!
The main thing so far is that inside seems to take longer to calculate than outside!
Thanks mate!
