Great link for MER color/3D images
Most people here have a great knowledge of Mars links on the web but just in case this one slipped past anyone, this is a site I visit often for quick and dirty color and 3D views of the rover raw picture files. They seem to appear here as soon as JPL releases them so I believe they're being automatically generated. Some of the 3d stuff needs human tweaking but you can at least get a general idea of depth from them if you cross your eyes enough.
Great site for instant color/3D
