To go along with the rover tracking feature in MMB2.0, there will soon be a "Rover Model" feature, where you can move a 3D model of the rover along the rover's actual path to see what it looks like in relation to the surroundings. UnmannedSpaceflight.com maestro Doug Ellison created the 3D rover model that MMB will use. Check it out an early version in these QuickTime movies:
Opportunity Sol 1061-1066 w/model
Spirit Summit movie
And there are some screenshots here.
