Two-dimensional shapes seem to hover weightlessly in space like a projection, but step slightly to your right or left and the whole image falls apart, becoming a chaotic assemblage of lines painted onto various surfaces in a room. Swiss painter Felice Varini has been transforming public spaces with his single-vantage-point illusions since 1978, and now he’s brought them to the Grande halle de la Villette in Paris’ Parc de lab Villette.

Varian invites us to look at the spaces around us in a new way, taking a closer look at the physicality of the world we have constructed around us through his somewhat disorienting optical illusions.

The spaces themselves are Varian’s true media, more so than the paint. Even when certain shapes and motifs are repeated, the result is different every time. “My work evolves in relation to spaces that I am in contact with,” he says.

The installations will be up through September 13th, 2015, and guided tours are available.
