M.C. Escher was a Dutch graphic artist, most recognized for spatial illusions, impossible buildings, repeating geometric patterns (tessellations), and his incredible techniques in woodcutting and lithography. Escher was a man studied and greatly appreciated by respected mathematicians, scientists and crystallographers, yet he had no formal training in math or science. When looking at his works assume nothing, and look for the unexpected. Just when you think you understand a piece you'll notice an angle that doesn't "jive" or that a building has sides facing impossible directions. Make sure and look twice, if you see figures in light (white) chances are they are duplicated right next to them in dark (black) and "meshed" together.
