The eye is considered to be the second most complex organ of the human body, but artist Leon Keer has found a way to fool it. Leon uses a lot of techniques and materials (including acrylic paint, solvents, tar, and other) to create his 3D street art that bends reality through optical illusions. He learned to paint through designing and producing large advertising murals for big brands such as Coca-Cola, and doesn't mind that his pieces are temporary: "Every street art piece is unique and belongs to the street and its residents, the temporary fact about this artform strengthens its existence," says Leon.
