American artist Jim Sanborn is probably best known for his mysterious Kryptos sculpture at CIA headquarters, or for his vast body of work dealing with radiation and nuclear experimentation. But it's his "Topographic Projections and Implied Geometries" photo series that looks most interesting to Earth-nerds like us. Shot at night, the photos use long shutter speeds and light projections to superimpose patterns onto rocky landscapes in Ireland and the Southwest U.S.
"On moonless nights, the landscape was lit with searchlights," writes Sanborn. "The landforms themselves are quite large, requiring the projector and camera to be, on average, 1/2 mile away from the subject landscape."
