I was this friday on this exhibition in frankfurt. Op art means optical art , or art meant to confuse the senses. There were some really good installations with mirrors, for example a room with glass floor and ceiling which gives illusion that there are multiple floors with people beneath it.
I got really excited by some posters giving an illuion of warping space. It remings me a bit of the works of Escher, the favorite artist of most mathematicians :-) Now I am trying to do something like this myself. Here are my first tries, i will post more later.
