Beautiful installation using light and architecture.
Here's the description from the artist, Pablo Valbuena's, website:
"Site-specific installation. Matadero Madrid. ES. 2010. Video projection on architecture.
Quadratura was the technique used in the baroque to extended architecture through trompe l’oeil and perspective constructions generated with paint or sculpture.
The site-specific installation presented at Matadero Madrid follows the same principles but manipulating space by means of projected light. The main axis of the room of Abierto x Obras is extended and the limits of the physical space dissolved."
