Title: Broken LCD screen

Animated fractalness! It's kinda like reducing/increasing the iterations on the Mandelbrot.
Sort of counts as 'nature' despite the actual screen being man-made I guess:

Plus color cycling :) Terrific!

It's almost certainly a form of "Diffusion Limited Aggregation" (DLA): http://apricot.polyu.edu.hk/~lam/dla/dla.html (http://apricot.polyu.edu.hk/~lam/dla/dla.html) Simulated using Ultra Fractal: http://makinmagic.deviantart.com/art/DLA-Style-Animation-95720811 (http://makinmagic.deviantart.com/art/DLA-Style-Animation-95720811) (http://fc07.deviantart.net/fs36/f/2008/253/b/4/Mandelbrot_Leaf_by_MakinMagic.jpg) (http://makinmagic.deviantart.com/art/Mandelbrot-Leaf-97506060) (http://fc07.deviantart.net/fs37/f/2008/246/5/8/V_by_MakinMagic.jpg) (http://makinmagic.deviantart.com/art/V-96801636)

It looks really incredible! Fractals in not natural nature :-)

I saw something like this in real life several years ago...
The "coloring algorithm" could be based on the "basins" of the cracks and the curvature.

Simulated using Ultra Fractal:
May I ask the fractal formula / coloring formula you used to do this ? I think that combining it with the 3D textures I'm playing with could be fun.

It's a plug-in colouring, just use mt.ufm:pixel as the formula and then set the outside colouring to mmf5.ucl:Generic Colouring (Gradient) Render=false or mmf5.ucl:Generic Colouring (Direct) Render=false. Or just use this: quickdla {

I had a try and did not get what I am looking for so far. I tried to plug the DLA formula in the coloring slot of a pixel fractal formula in a trapshape block for trap shape or trap texture parameters of the main MMF orbit trap gradient wrapper, but it seems that the "pixel-based" nature of DLA is a too strong constraint to really combine it with other shapes and textures.
The best I could do so far is an image with traditional trap shapes, and the DLA as a 2D texture to color the trap shapes. But I would like to have 3D slope+lighting texture "inside" the DLA cracks : does that sound feasible?

I need to write a more general version for that sort of use. Not sure what you mean by slope+lighting here, but the formula can be used in direct mode like this: quickdla {

That is possible the coolest active fractal display I have ever seen. Others like the animated ones aren't as raw and colour mixed as this.
