I've drawn up an improved Urban Geomorph template.
The way I'm using it, it's a large image. It's designed to be used as an A3 sheet (420mm x 297mm) to produce a hex that is 300mm across the points. But if you're interested in using it, there's no reason why you couldn't scale it down to A5, to produce hexes that are 150mm across the points (or whatever other size you wanted).
Here's the link.
Feel free to use it, but please tell me if you do, I'd like to see what is done with it.
