Some Optical Delusions

You really won't believe these illusions:

		1. Which circle is larger? Believe it or not, they are both exactly the same size. Don't bother measuring them, as I have already done that.
		2. Which horizontal line is longer? Believe it or not, they are both exactly the same length.
		3. Which square is darker? Believe it or not, they are both equally dark.
		4. Parallel lines? Believe it or not, the black lines are parallel.
		5. Straight line? Believe it or not, the thick black line is actually straight.

Now, don't you feel stupid that you got all of those wrong? Had this been an IQ test, you'd still be reading Dick and Jane (are they still around?).
