So Subtle

These two images are the same colors as those yesterday- - in fact they are the same images, but rotated. 

Does the shape of these rotated images feel different to you than the images you studied yesterday?  They should. 

These are the types of subtle differences that make us love or hate a painting or a photograph and help us decide what we want to hang on our living room wall and what painting we wouldn't carry through the front door.
