Street art has always challenged the way we see the world, but some artists go even further, transforming walls, streets and buildings into astonishing visual illusions that blur the line between reality and imagination. Showcasing the work of more than 50 street artists, graffiti writers and muralists from around the globe, Optical Illusions in Street Art explores the creative minds behind artworks that manipulate perspective, depth, colour and scale to reshape our experience of urban space. From monumental 3D murals and anamorphic paintings to geometric abstractions and playful interventions that interact with their surroundings, these artists invite us to look twice—and then look again. Alongside spectacular photography, exclusive interviews reveal each artist's creative process, influences and technical approach, offering a unique insight into the challenges of producing large-scale works that depend on precision, architecture and the viewer's point of view. Inspiring and visually captivating, this richly illustrated volume celebrates the artists who transform our cities into immersive works of art and encourages readers to discover the extraordinary hidden within the everyday.
