Ok! what about these two ones? grin
It's a mix between KIFS and msltoes' approache. The DE is not perfect: there are still some discontinuities but it's good enougth. Unfortunately those discontinuities are more severe if one changes the scale, offset or apply rotation. That may mean that hybrids would give some sand effect.

I won't implement, I put too much effort for mine already to eliminate discontinuities, so won't restart again sorry! Azn

Sorry 4 Necroposting but I need to do it  grin // this is fragmentarium/koch02's frag. modified this way: define a cube (using distance field technique)  and use its length instead of z.
Code:
float cube=sdToBox( z.xyz, par );
return (length(cube)-2.) * pow(Scale, float(-n));
One can use IQuilez's library to call the definition of sdToBox; par is vec3(-0,90568).
Number of iterations is 4.

Number of iterations here is 11

  Made a non DE .frag for it. Also- the non DE version combines VERY well with other formulas.  Actually, if you look at the way I implemented bailout in the Kochy Mag Mandy, I think we can redo other formula types with this dual bailout method and get really awesome results.    Duhh..

  I decided to attach them, but they aren't "finished", in other words, I might have an idea or 2 to implement and some organization to do, such as rename various variables so they are easier to understand.  A couple of cool presets for the Koch Mag Mandy.  Should rename it the Kochy...  Will post a few images later.  Pretty awesome.

  This image is a blown up "Metal" preset.  Set the colorspeed and orbitspeed high for "Metal" coloring.
