op-art-creators

I am seeking an op-art club, I am sure there is one somewhere...Didnt find it yet ! If you are aware of such a club I would be glad to share my interest in op-art. Thanks !

You just have to check one black point then check an other and you will see something weird. Will you be able to see it? ;) And one other? FYI, A and B are the same color!
