Being on top of the sand dunes is truly bizarre. It was so bright that I could see perfectly well without glasses (bright light = small pupil diameter = small aperture = high depth of field), and is pure monochrome white for miles in every direction. Not that I'm likely to ever know, but that is probably what it felt like to be on the moon. It's only missing the black sky and 1/6 gravity.
