Yeah ... it's big, rough and blue ... but just a demonstration, don't ya know [;)].
Also, it takes some artistic work to make it look pleasing on parts of the map (look at road area, see how it looks aweful around the blue with the extra white sides).
The Grid can be any size ... The SceneXML defines this. In the SS, it's roughly 17m square / 25m diagonal.
I can write up a tutorial if anyone cares ... however, Stridor's tut #3 will probably contain the instructions on how to do it. I'm not much a of tech writer and I don't know if there's an easier process and maybe all the requirements to get it done right and cpu friendly.
