These incredible optical illusions are not projected onto the human body or created in Photoshop, they are actually painted directly onto human skin by artist Natalie Fletcher.
Each painting is done free hand with an airbrush and the result is truly mind-bending. Cleverly shaded areas and the variation of tones in the vibrant colours create the illusion of depth, making parts of the body art jump out at you.
Fletcher has just started a new project titled 100 Bodies Across America in which she will paint two bodies from each state. You can follow her artwork via Facebook.
