Optic : Optical effects in graphic designSome art forms have had more of an impact on the language of graphic design than others, but not many have helped contribute the same dynamism, energy and vitality as Op Art. Graphic designers today are rediscovering the optical art of the 1960s with delight, revelling in its experimentation and unexpected outcomes. It is the purpose of Optic to attempt a survey of optical effects in graphic design and to help distinguish their various forms.
