Need some programming help

[ravells]

I'm doing a map commission and I need some passable outlines of larger buildings which are more than just rectangles. There is a free piece of software called 'context free' which I think would allow one to make dozens of random shapes in a building-like form. Below are some examples I've taken from their gallery of the shapes it can generate.

The only problem is that I am not a natural coder. I suspect the code to produce black building silhouettes would not be difficult for someone who was used to writing code. I don't need the buildings to be organised in any particular way, I just need lots of buildings generated so I can pick the ones I like and drop them into photoshop.

Can anyone help?

Thanks in advance,
