Optical Illusions

Two lines, one height - New Optical Illusions Videos

The two black vertical lines are actually the same size. this was originally a single still frame (the first frame of the video), and from that it’s hard to see that the lines are the same height (though print this out and use a ruler and you’ll see they are). i created this quicktime to illustrate just how the illusion works. all i do in the video is slowly take away the other elements in the picture.

i never alter the lines as i erase other parts of the image. both lines are exactly the same height, but the other diagonal lines around them give the illusion of one being smaller than the other because our brains perceive the horizontal lines coming together as moving away from us into the distance, thus interpreting the “rear” black line as larger.
