Ann Veronica Janssens is best known for her use of ephemeral materials such as colours, artificial fog, water, and light. Objects themselves are not very prevalent in her work, but properties of matter (gloss, lightness, transparency, fluidity) and physical phenomena (reflection, refraction, perspective, balance, waves) are rigorously investigated for their ability to destabilize the very concept of materiality. The implementation of those elements lends itself to the excavation of the balance between the defined and the undefined. Her work evolves around cognition, reflexes, meanings, and the human mind, and serves to explore perception by unbalancing both perceptive and sensory experiences. By using different means of presentation – installations, projections, immersive environments, mist rooms, urban interventions, sculptures – Janssens invites the viewer to cross into a new sensory space, a space that finds itself on the borderline of dizziness and bedazzlement. A loss of orientation and control becomes linked to questions of perceptual psychology.
