Anamorphic drawings or paintings can be seen in proportion in a reflective cylinder or cone and, usually, from a particular point in space. When viewed from the wrong angle or without the reflective viewing device, they look stretched and abstract. The technology for producing anamorphic drawings and paintings “stretched” the rules of single point perspective developed in the Renaissance.
