When the visitor stands facing the installation, their presence is captured by two depth cameras. Their silhouette then appears simultaneously on both planes: emerging and viscous in the oil spill on the back wall, and on the tulle nearby, enveloped in iridescent, multifaceted colors. As they move along the installation, they see themselves doubly inscribed within the material. They are oil: this is the literal meaning of the installation's title.

The superimposition of the two projection planes creates a striking depth effect: the visitor naturally perceives the planes sliding relative to one another as they move, reinforcing the illusion of physical immersion in the substance. A generative and immersive soundtrack accompanies the flow, strengthening the sensation of the material's physical presence.
