Video: Optical Illusion, Julian Beever Chalk Drawings.
"Julian Beever "Pavement Picasso" is an English, Belgium-based artist who has been creating amazing 3D pavement chalk drawings since the mid-1990s. His works are created using a projection called anamorphosis, and create the illusion of three dimensions when viewed from the correct angle.
Besides this pavement art, Beever also paints murals and oil paintings."
