The Telefonica Foundation in Madrid, Spain, presents the exhibition Certezas Efímeras [Ephemeral Certainties] from February 22nd. The individual show features Nido de las Nubes and Changing Rooms, two of the most iconic installations of the artist Leandro Erlich (Buenos Aires, 1973).

Although in different ways, both works deal with similar concepts, inviting the viewer to question the dimension functionality and causing a mismatch between what the mind expects and what the eye perceives.

Ephemeral Certainties runs until April 23. For more information visit the
