Wikipedia: From the Greek “kaustikos,” meaning “to burn.” In optics and mathematics, a caustic refers to the envelope of light rays that undergo reflection or refraction on a surface or curve.

The artwork references the terrorist attack on Charlie Hebdo that occurred a few months before the exhibition (in French, caustic is used to describe ‘’acid’’ humour).

Two pieces of theatrical gelatin rolls (one red, one blue) are crumpled and intertwined on the gallery’s white wall.

The attractive kinetic aspect, like a giant candy wrapper that changes with the daylight and the viewer’s movement within the exhibition space, contrasts with the static and terrible nature of the work, like a photograph of a solidified, scarlet waterline (in a swimming pool).

From a certain time of day, the sun’s rays entering the gallery reflect off the artwork, forming caustics on the floor.
