Insane 51 (real name Efstathios Tsavalias) is a Greek visual artist internationally recognized for pioneering the art of 3D Double Exposure Murals. By merging photorealism, graffiti, and layered color separation, his work forms dynamic visuals that reveal dual images when viewed through red and blue lenses. His art often explores dualities—life and death, presence and absence—delivered through striking, hyper-detailed compositions.
Emerging from the graffiti scene in his teenage years, Insane developed a unique visual language that quickly captured global attention. He has created large-scale murals in cities across Europe, the Middle East, Asia, and the Americas, leaving his signature mark on walls, facades, and public spaces around the world.
Beyond murals, his studio practice focuses on original canvas works and limited edition prints—translating the power of his street art into collectible forms. Currently based in Greece, Insane continues to expand the boundaries of visual storytelling and perception through both public and private art.
