These amazing optical illusions have been created by Ukrainian artist Oleg Shuplyak.
Merging portraits of famous figures from art and fiction with landscapes and images from nature, his work requires a double take - or in some cases, several minutes of staring - before the secrets of the visual illusions reveal themselves.
Famous artists, cultural figures and characters to be given Shuplyak optical illusion treatment include John Lennon, Pablo Picasso, Sigmund Freud, Charles Darwin, Paul Gauguin, Zeus and Uncle Sam.
Each optical illusion reveals two separate images, some far quicker than others. But all display an extraordinary level of artistry and a playful take on classic imagery.
Shuplyak was born in 1967 in the Ternopol region of the Ukraine, and studied architecture at the Lviv Polytechnic Institute.
