However, they of necessity introduce gross distortions at the edges (away from the center point of the projection).  This is also true of projections like Mercator and your example map, but those projections are common enough that they "look normal" to most people.

	Anyone have a link for a brief desctiption of the different 
projections, for s non GIS people?

	I'd like to render our maps onto a flat-model, just not sure which 
projections do what.
