Τhe hovering car without wheels, also called the hovercar, is a constant fixture in science fiction films, video games and comic books, and a long-standing dream for car lovers and technology fans alike. This dream is also shared by French photographer Renaud Marion, who creates images depicting hovering cars in everyday urban settings. In his ongoing photographic project titled ‘‘Air Drive’’, Marion combines retro car designs with futuristic technology, a project driven by his childhood visions of how the world was going to look like in the future.

Sandrine Kerfante has had a fascination with “doubles” ever since meeting her mother’s twin as a child. In 2012, this lifelong captivation inspired her to create a blog called twin-niwt, which celebrates photographs of doubles in all their forms. “I’m fascinated by the idea of the duo, repetition, symmetry, reflection, mirror games and all the symbolism associated with it”, she says. “I think it’s a topic often present in photography, more or less consciously”.

William Gibson is not one of the authors that spits out novels like a machine – in his long and fruitful career he has only published 11 novels andof short stories and articles in the tens each. Still his impact on modern literature was huge – the “noir prophet” of the cyberpunk subgenre (that he was one of the pioneers of) has predicted the rise of reality television, virtual reality, video games and the internet. He is a Hugo and Nebula award winning science fiction writer, with a special eye for what the future might bring.
