By definition installation art uses interesting material to transform a space and create an experience. It implies a dissolution of the line between art and life. It makes us stop and notice our surroundings, it involves us so that we forget for a brief moment where we are, as we become a part of the art itself. Here we've collected ten of our favorite indoor and outdoor art installations. We hope you enjoy them! Butterfly Installation at Dior Homme Paris by Andrea Mastrovito

9,000 fantasy like butterfly silhouettes making their way through the boutiques white walls and ceiling. [link] Light Play at Luminato by Michael Levine and KPMB

200 illuminated PVC balloons were tethered together by an intricate web of nautical rope and fitted with lights that were controlled and programmed to change color to the sound of the audience and live music below. [link] Art installation at Clark Shoes International Headquarters / ROSO

The installation itself was developed from a single observation – Light is only seen when reflected. A light beam coming through a window is only visible because light is reflected in the millions of dust particles floating in the air.

A multi-faceted installation which reflects fragments of surrounding buildings. While moving around the sculpture, the reflections on the glass continuously change. In this way, the viewer becomes an integral part of the installation and its complex reflections. As day becomes night, the installation takes on a whole new life. The structure is lit from within and the reflective, color-distorting film on its surface becomes transparent adding to its fragmented perception theme.
