The panorama guy (that's what I call him) Jeffrey Martin of 360cities made something so wonderful it's literally out-of-this-world: a fully spherical, interactive view from inside the Victoria Crater in Mars, from photos taken by the Mars rover Opportunity.
Link [Flash 9/Quicktime]- Thanks Jeffrey!
The little humanoid of Mars is nowhere to be seen, though.
The sundial is what proves all photos are edited.
