Escher
The Dutch artist M. C. Escher was famous for drawings in which interlocking people and animals combined to tile the plane. A number of other artists have followed in his footsteps. Other pages here include work related to Escher's drawings of polyhedra and impossible figures.
Escher-inspired animorphic art by Kelly Houle, including "impossible figures" such as linked Penrose tribars.
David Bailey's world of tesselations. Primarily consists of Escher-like drawings but also includes an interesting section about Kepler's work on polyhedra.
Computer art inspired by M. C. Escher and V. Vasarely, H. Kuiper.

Delta Blocks. Hop David discusses ideas for manufacturing building blocks based on the tetrahedron-octahedron space tiling depicted in Escher's "Flatworms".
Sylvie Donmoyer geometry-inspired paintings including Menger sponges and a behind-the-scenes look at Escher's Stars.
Escher for real and beyond Escher for real. Gershon Elber uses layered manufacturing systems to build 3d models of Escher's illusions. The trick is to make some seemingly-flat surfaces curve towards and away from the viewplane.

Gallery of interactive on-line geometry. The Geometry Center's collection includes programs for generating Penrose tilings, making periodic drawings a la Escher in the Euclidean and hyperbolic planes, playing pinball in negatively curved spaces, viewing 3d objects, exploring the space of angle geometries, and visualizing Riemann surfaces.
