Rafael Lozano-Hemmer is a Mexican born artist who graduated from Concordia University, Montreal, Canada with a B.Sc in Physical Chemistry. He is an electronic artist who develops mainly large scale interactive installations in public spaces. Lozano-Hemmer uses robotics, Internet and mobile phone links, sound and sensors to create his pieces.
His instillation 'Homographies' is an interactive installation that uses 144 robotic light fixtures that are controlled by 7 computerised surveillance systems. The piece works on the premise that the vanishing point is not architectural, it's connective.
This means the piece is determined by who is in the space at any given time and as a result of this changes accordingly. The fluorescent lights rotate as people walk under them, this creates patterns of light that are 'paths' or 'corridors'
