Advanced noise workflows

[Neon Junkyard]

So this is more of a general inquiry of some good workflows rather than a specific question but I am trying to make detailed grunge maps essentially in houdini and I was wondering what some advanced workflows for generating complex procedural noise and general patterns might be.  Basically I am trying to recreate some of the things people have been making in, for instance, substance designer, while staying in Houdini. 

 

A couple examples- 

some of the grunge maps from substance.  I'm sure a lot of them are texture based which I would like to try and avoid but not at all costs

making something along the lines of the popcorn noise this from Mari (like the sparse cracking patterns)-

or this where they talk about the multiFBM features, towards the end when they start to get really complex-

Then not necessarily for grunge maps but some of the colorful abstract stuff lee griggs has been doing with those xgen renders.  Not necessarily how he did the effect but moreso how he generated the color patterns they were based on

Then the gobstopper-like layered noise happening here-

I know you can do things like distort the position coordinates of a noise with another noise, and you can create an FBM type swirly look by pumping noise into the translate of a transform matrix and then piping that into another noise, and then you have things like multi-fractals in a for loop and unified noise with built in fBm but that all still looks very CG to me and still falls shot of mimicking real texture maps, which require UVs and can have noticable tiling and repetition etc.  So there is that, and then a lot of stylized procedural patterns interest me so just looking for some good workflows to accomplish some of these interesting effects. Thanks
