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.
