43) Illusion of Motion

One way to achieve the illusion of motion is through a repeated figure, which is very common and shows the same character multiple times to show movement of the character.

Comic strips are a great way of showing motion through repeated figure because comic strips usually consist of only a few characters and they are usually in every frame and they move.

Another way to show motion would be to have a blurred outline which is based on photography which when a photo of an object in motion was taken by a camera with a slow shutter speed the photograph turned out blurry.
Below is a drawing that shows motion through blurred lines giving the impression that the figure is walking.

The final way to show motion in drawing is to have multiple images of the same character or form in an overlapping sequence.
A perfect example of this would be the picture below that shows a snow boarder multiple times doing a flip.

42) Spacial Puzzles

Equivocal space is a spacial puzzle in which you can not be sure which object is on top or in the background.
Here is a perfect example of equivocal space.

41) Multiple Perspective

Multiple perspective is looking at a single object from more than one vantage point simultaneously. This creates a single image that is not what the eye would see in real life but that the artist knew was there and recognized.

Picasso was very popular for doing this in his paintings. He notices that every woman in this painting has a face. Even though the woman in the bottom right corner is not even facing the audience you can see her face.

40) Amplified perspective

amplified perspective is a dynamic and dramatic illusionistic effect created when an object is pointed directly at by the viewer.
Uncle Sam pointing to the viewer has been done and redone many times in different forms and fashions but it has gotten the readers attention because of its amplified perspective. Uncle Sam breaks the fourth wall and recognizes the viewer.

36) Illusions of Space

Overlapping is a common technique to show space because it creates depth by letting the viewer see that there are some objects on top of others which means that they are closer to the viewer.
In the photo below there are three horses and the one on the far left is the closest to the viewer because it is on top of the others and the one on the far right is further away from the viewer because it has other horses overlapping it.

I'm just kidding, I know they are butterflies

Vertical location is another depth cue that helps us to see space. Things that are usually higher up on the page are more into the background your eye wanders. Just like in the picture below you are seeing a landscape in which if you start at the bottom of the page and look up toward the top you will end up further away.

Another tool used to show space is aerial perspective. Aerial perspective is the use of color to show depth, for instance things getting cloudier or less clear, possibly even darker, as they move backward in space.

In this picture of a woman you can tell that she is closer because not only is she in front of it through overlapping but she is also more clearly defined and not as blurry.

The final illusion of space would be linear perspective which is a rather complex spacial system based on   vanishing points and how parallel lines appear as though they converge as they get closer to the horizon line. The most common example of this is railroad tracks because everyone knows what they look like and everyone knows that they are going to be equally spaced down the line however they seem to disappear if you look down a set of tracks that move in a strait line toward the horizon.

35) Scale Confusion

Scale confusion is when there is an object in a piece that is not the correct size according to the hieratic scale, which states that things get smaller as they are further away from the viewer and bigger as they get closer.

This picture shows a donut that is a sign on a building and it is pretty large being dunked into a small cup of coffee which we know is not possible but they have created this illusion through scale confusion.
Another great example is these two girls standing on a giant banana, which is not actually a giant banana it is a banana in the foreground while they are in the background.

33) Rhythm

Progressive rhythm is one form of rhythm in which repetition is present however the shape changes in a regular manner as it progresses leaving a sense of sequential pattern.
