What's right-side-up? What's up-side-down? It's difficult to tell in these playfully bizarre photographs by French photographer and art director Patrice Letarnec. The hilarious series, entitled Head Over Heels, documents a number of people as they walk around the streets of Paris on their hands.
To create the optical illusions, Letarnec places his subjects in outfits that look correct when up-side-down. When each person flips to a handstand, the illusion suggests that oddly balanced headless figures are taking the phrase "head over heels" a little too literally. Thick legs appear to be arms and thin arms look like tiny stick legs in each disproportionate portrait. The odd series will certainly inspire a double take to figure out what's going on!
