Bagi László (1962) graphic designer, specialises in 21st century optical art (op art). His works transform flat shapes into beautiful 3D objects. Represented in 3dimensions, the circles turn into spheres, squares and rectangles into cylinders, cuboids and cubes. His main theme is the interaction between these objects, such as reflection and transparency. In his opinion, the computer graphics have reformed op art and revolutionized the representation of images. The special colours and light effects can be helpful in developing stereoscopic vision and can be great teaching aids.
