Take a Look

There’s more than a grain of truth in the maxim, “It all depends on how you look at it.”

Dutch artist Marrits Cornelius Escher (1898-1972) proves the point with his etchings of impossible structures at the mind-boggling website mcescher.com. In addition to fantasy buildings with tricky perspectives, there are six galleries of symmetry drawings, including Escher’s famous repeating patterns of geometric shapes, such as flying fish in a herringbone formation.
