Rectangles are boring.

Albers is depassé as are concentrici squares.

Given a chance, doesn’t it feel and look a lot better being a little bit “irregular”? Especially so if the frame is conspicously “straight”.

And of course size matters, as does the environment, particularly if the artwork is not meant to sit (stay put?) in a museum, but is diplayed on a long fence wall di cinta, fronting a busy street, where motorists are often blocked in the traffic and are perfect captive audience.
