Back on July 22nd I posted the optical illusion with the cat floating around (Optical Illusion from Yahoo) now they are back with two Illusions, see if they bug you out as much as they did me.

From yahoo.com:

These “fish” may appear to be wiggling, but the only thing changing in this animation is the color.

The two birds in this image are identical. Not just in size and shape, but in color too.

Don’t believe us? Check out the same image with the background removed.
