I don't know if this has been asked before because I don't know how to put this in a phrase. I'm looking for a smart way to draw houses in a city map done with GIMP.

I know the City Designer by ProFantasy has a feature where you can draw a simple line to get a street with randomly shaped houses. Maybe this has been implemented as a GIMP plugin? Or maybe there is a smart way of using brushes for this task?

Please enlighten me! I need a quick an dirty city map in less than 24h or my gaming group will lynch me
