Digital creation

Olivier Ratsi, visual artist

I want the viewer to see things differently, as if they were at the foot of a mountain, in order to question the capacity of our gaze to metamorphose.

Olivier Ratsi's light installations appeal to the viewer's senses, to better question how digital technologies resonate with techniques of representation inherited from the Renaissance. Several of his creations are available on IFdigital, the website of French digital creation.

Born in 1972 and based between Paris and the Cévennes, Olivier Ratsi has been working for nearly two decades on geometric and chromatic experiments made possible by digital technologies. A pioneer of VGing, an artistic discipline that consists of dressing up spaces with video and light projections, he founded AntiVJ in 2007, a collective that aims to reinvent how technologies allow us to interact with a space. Using mapping techniques, Olivier Ratsi adapts to the location's architecture, with site-specific and immersive installations that have been exhibited throughout the world. After a first retrospective in Marseille in 2020, held in a temporary exhibition space, the Gaîté Lyrique recently devoted a major exhibition to him, entitled Heureux soient les fêlés, car ils laisseront passer la lumière (2021). 

Olivier Ratsi's work questions objective reality and the way we perceive time, space and matter. His works, rooted in the theory of perspective as developed since the Quattrocento, are based on a rigorous reflection around space, its constraints and its illusions. DELTΔ, produced in 2014 with his long-term musical collaborator Thomas Vaquié, thus experiments around anamorphosis, a phenomenon that plays on the deformations and recomposition of images according to the viewer's position. More recently, Spectrum (2020) is an installation composed of luminous LED frames that play on natural perspective effects. 

Regularly exhibited internationally, Olivier Ratsi is also frequently invited to prestigious events related to digital art, such as Mutek (San Francisco), the Microwave International New Media Art Festival (Hong Kong) and the Fête des Lumières (Lyon). His works are conceived above all as experiences in which spectators are able to reappropriate the light, the music and the scenography. His approach is therefore both interactive and sensitive, designed to question our senses and our ability to interpret information and perceptions. Sometimes monumental, always at the cutting edge of technology, Olivier Ratsi's installations nevertheless appeal to our intimate feelings, questioning how our sensations are redeployed in the digital age. His work is currently featured as part of Chroniques, Biennale des Imaginaires Numériques, in Marseille.
