“A girl arrives at the parking lot wearing tiny leather shorts and sits on the back of a bike with a horse power of more than 1,000 CC. Next to her a man gets ready to ride, wearing a skeleton mask. It’s more than a fashion show, it’s an extravaganza on two wheels along Chinese roads”. – Carlos Barria. Photo: A couple rides their motorcycle at the Qian Dao Lake rally, on May 11, 2013.

Earlier this year, Belgian film-maker and artist Vincent Bal stumbled upon an uncanny resemblance to an elephant in the shadow of his tea cup. This gave him the idea for Shadowology, a series of doodles that interact with the shadows of simple, everyday objects: a banknote, some ice cubes and a flower, for example, can turn into a church, a woman and a hippy. “I draw a few lines and I get my image. It’s really the shadows that inspire me”, Bal says. Here: “Stonedog”. (Photo by Vincent Bal/The Guardian)
