Given that we can make ovals, sqaures and what nots with Mappoint, why not also add a tilt to them?
Ovals on an axis could nestle quite nicely in say, a topo map of a valley if you wanted to indicate something that's in the floor of it, and not on the cliff sides.
A box turned 45 degrees is a diamond, which might appear better then a push pin or a dot, AND scalable to show say intensity. A series of diamonds with the largest of them showing the largest diamond mines?
An imported shape could show a meter, with the needle going from 0 degrees for the least impressive all the way to 90 degrees up for the hottest areas.
These are just examples, but I'm pretty sure others will think of more.
