Rădvan's "Torrid Geometry" cycle is experimental in terms of both form and technique becoming a turning point in his oeuvre. While maintaining the powerful colors and the big format canvases familiar from his previous paintings, in his recent works he has replaced the flat collages with shapes made of cardboards. He was driven in this artistic process to abandon the conventional materials like paper and canvas and use common cardboards with different kind of textures in his quest to render fantastic three-dimensional scenes.
