Which line is actually a line? Look at the optical illusion image above.
First, imagine that C connects with point A. It seems like it could
work. Then see if C connects with B.... it appears that that is a possibility
too. To see the real answer, you'll just have to hold a straight edge
up to the screen and use a magic marker to connect the dots. Don't worry,
white out will take care of the black mark on your screen.
