Many claim that we are now living in a perfect simulation, one in which each ray of light is quantifiable and apprehensible, like an element rendered in 3D modeling software. Quantum physics takes an entirely different approach to light, treating it as a dynamic relationship between a wave and a particle that can never be captured simultaneously. Art appears to be torn between these two visions. It is at once completely tangible and absolutely impossible to apprehend. Created by Alona Rodeh and Karolina Hałatek, the pieces comprising Ray Tracing are perfect instances of artworks that produce an extraordinary field of interaction, be it through light, sound, or some other form of energy that can never be truly touched, seen, or comprehended. It is fully abstract, like a simulation, or absolutely indeterminate, like a quantum.
