Above: Move Your eyes From The Left to The Right Of The Image And back
And Forth. Do You See parts Of The Image Spinning?  
I can Assure You It Is NOT,
It Is Your Brain  Playing Tricks On You.
Above : Move your head close to the screen. Do the perfect blue squares appear to be distorted?
Absolutely... This is due to the black lines in the back moving and twisting it in your mind.
What an eye trick!
It's two illusions in one!
First of all, it appears that the lines are not straight, which in fact they are perfectly straight. Look at
the blue gaps between the arrows and it looks like they are slanting either up or down, depending
on which one you look at.

Next, because of the color choices and how this is laid out, if you move your eyes up and down
across the image, the arrows will appear to shift slightly. This also works if you just stare at the
picture for awhile. The tricky thing is that the arrows move in the opposite direction of how they are
pointing
