Neil Freeman is an artist and urban planner in New York who does some interesting artistic experiments with maps on his website, Fake is the New Real. His newest project is dividing up the nation into 50 states with equal populations (about 6.175 million people per state).
The text that accompanies the image on his website is a little confusing. Freeman wraps up by saying that this is just a piece of art and that he's not seriously suggesting a change to the Electoral College -- but everything that proceeds that statement seems to be a serious attempt to weigh precisely that prospect.
Regardless of Freeman's true feelings, I don't have any truck with desires to reform the Electoral College, but this is still fascinating if you're interested in population distribution, political geography, etc. (You'll have to click thru to see it at full size):
