The starting point for Várnai’s investigations, which he carries out in diverse media, is usually a very simple, everyday situation or thing. His objects and images (projections) are characterized by a reduced set of tools, a simple layout, pairing and omission. His installations and object-collages tend to consist of various objects of use. His assemblages are marked by a conceptual and poetic quality, and an air of meticulous DIY. The creation and destruction of illusion, and the mutual references between signs, texts and objects, are also hallmarks of his activity.
Several of his works centre on some physical phenomenon, and are charged with philosophy and humour. The viewer often becomes an element in the piece when it is her movement in space that produces a conjunction or an image. Várnai often deals with epistemological problems, the possibility of understanding the world is one of the fundamental issues that his works grapple with. His is an aesthetic of refuse, of the recycling of objects and situations found.
