I do not get it. Square A is Black and Square B is White?

Nope. They are both exactly the same shade of gray. (rgb #787878 to be exact).

You can remove any optical illusion part of this by simply using your hands to block out any surrounding squares, shadows, and colors. You can plainly see that square A is some shade of gray and that B is some shade of off-white.

I really like the ones used in Bloch and Gafter's Java Puzzlers too.
Here's another well known illusion:

Finding it pretty hard to perceive the direction of rotation as anti-clockwise. The wiki link says, if you perceive the touching leg (to the ground) as the right foot (which I am unable to perceive), the rotation will appear to anti-clockwise.
Heck, I only see it in clockwise direction.
