Find two people with similar figures. Take a picture of each in the same position and from the same angle. Then you'll be able to line up the pupils and regurgitate this same effect. Especially be cause of the rapid changes, the mind comfortably judges the two figures as remarkably similar, but they are really quite different with few similarities.

The most easily seen discrepancy is a group of things that we can lump together as "fashion." The hair, clothing, and accessories (jewelry) make up this group. By these things, we easily recognize that there is change going on and, in fact, in a repeating manner. Beside that, the obvious difference is the background.

The similarities of the photos include:

• the angles of which they were shot,
• the exact positions of their right pupils (on the left side in the photos),
• the hues of their eye colors,
• the sizes and shapes of their smiles, noses, and cheeks.

It should be mentioned that the author of this animation has cleverly lined up portions of the women to make the change somewhat seamless; notice the left area of the images, particularly the alignment of the face and jaw. On the right side of the images, the faces do not match up. This is also shown in the eyes, as their left eyes (right side on the images) are misaligned. And it's possible that fine size/resolution adjustments were made to one of the original images, as it's not very common for two separate photos of two separate people to be taken from the exact distance.

The differences that can be seen include:

• the tones of skin,
• the positions and appearance of eyebrows,
• the positions of the eyes and eyelids (their left eyes),
• the amounts and colors of makeup (especially eye makeup),
• the positions of the jaws (put a finger over the eyes and noses of the animation if you don't already notice this),
• one of them has their teeth fucking whitened,
• and presumably their tits...

They are not equal, they are not the same, and you can still fap to either one. Enjoy.
