Math, art, travel, photography. What's not to like?
For some reason, probably all of the above, this photo of "Seventeen parallel flowlines running between Flow Station 2 and Drill Site 3, Drill Site 9, Drill Site 16, Drill Site 17 and Endicott at the Prudhoe Bay Oil Field" really struck me this morning when I read David July's Mount Sutro post, The Linear Perspective Orthogonals.
