Interactivity lies at the heart of Danish artist Jeppe Hein's playful works, which focus on facilitating "the visitor's direct and physical experiences" of art rather than "passive perception and theoretical reflection".
Similarly to Rafael Lozano-Hemmer, this is often achieved through the use of sophisticated technology, although Hein's emphasis is less on spectacle and more on the ludic possibilities of art.
His Moving Benches, for example, are programmed to move unexpectedly through a gallery space when sat on, an unlooked for yet humorous interaction.
The artist's desire to engage and entertain has led to an increasing number of works designed specifically for public spaces, such as Appearing Rooms, above.
Consisting of several adjoining 'rooms' delineated by walls of randomly rising and falling water, the installation takes on the aspect of a game as participants attempt to move from space to space without getting trapped - or soaked.
Unsurprisingly, it's a piece that proves immensely popular whenever shown, fully meeting Hein's own dictum that "it is important for me that my art is not only exhibited in the context of the 'artworld', but also seen and experienced by people who usually don't visit art museums."
