Is there a rock wall generator? In Lego store, and on many photos on the Internet, I've seen vertical "rocky" walls made of slopes and simple 2x1 bricks. For example this one.

Is there a software that would take wall length and generate a semi-random rocky-looking wall? Something similar to sphere generators we all know and love?

Designing such wall by hand in LDD is a time consuming and not really funny task, and I'd like to avoid it, if possible.

Note: I tried dropping models from Thingiverse to Brickify, but  Brickify does not use slopes and there is problem with scale.
I was able to integrate this into a research project applying context free grammars:



This is not a polished software package, and the design is a bit esoteric given that I started with the goal of applying context free grammars to a practical problem. Hopefully there's something in there that may be useful to someone. :)
