Dutch artist M.C. Escher is best known for his "often mathematically inspired woodcuts, lithographs, and mezzotints. These feature impossible constructions, explorations of infinity, architecture, and tessellations" to quote Wikipedia. In other words, the dude was a freaking genius. Check out these fabulous 3D color renditions of "Relativity" which happens to be one of Escher's most famous pieces of art.
I absolutely love this video. This is a beautiful animated amalgam of four works of art produced by Marcelo Ricardo Ortiz from the Vancouver Film School. Ortiz calls his work Guernica after Pablo Picasso's masterpiece about which Lunatica posted a marvelous 3D animated rendition a while back. Featured in this video are also Vincent van Gogh's Room in Arles which was also showcased in Lunatica in two beautiful videos not long ago; Salvador Dali'sThe Persistence of Memory and Dutch painter M.C Escher who is famous for his gravity-defying etchings and illustrations such as Relativity which is being featured in Ortiz' fabulous work. Sit (or stand if you please) and enjoy this beautiful work.
