How's this for fun?
Go to http://space.jpl.nasa.gov/ and use the simulator to find the view from one planet to the other - your choice! Particularly freaky was viewing Mars from one of her moons and seeing Earth as a blue marble in the distance.
FYI - Mars just rose over our neighbor's house...so if you're looking for it, find Kansas City on a map and look up from there. I think.
