Here is the Nasa website for the Mars Rover, and you an check out some really cool panoramic pictures that they have assembled (in various sizes). If you really want a hoot, turn oin your AM radio and listen to the Coast to Coast guys speculating about the images.
BTW- I just love radio, and Coast to Coast is a lot of fun to listen to. Most of the topics and people are way out there (last night they were talking to time travelers), but for some reason I just think it is a great show. Plus, it has the best bumper music ever.
