Climb It.

Once the "Dune Flyer" has descended the dune, they have to make the less graceful ascent.

When I created the original Dune Flyer image, linked above, my "painting" skills in the Picnik editor weren't as finally honed as they are now.  For instance, I didn't know then how to create subtler color tones, which is why the model here, a former college classmate,  is no longer a bottle blonde, but has hair  much more her natural color.
