What is an impossible object? Impossible objects, such as this impossible heart, are optical illusions. Our brains are programmed to interpret two-dimensional drawings such as this one as three-dimensional objects.
Impossible objects, however, seem to defy geometry when viewed as a three-dimensional object. They could not exist in the real world.
The impossible heart is based on the Penrose triangle, also called the Penrose tribar or impossible tribar. This impossible triangle was first created in 1934 by the Swedish artist Oscar Reutersvard.
It rose in popularity during the 1950s due to the work of psychiatrist Lionel Penrose and his son, Roger Penrose, a mathematician, from whom it derives its name.
The impossible heart can be used to represent never-ending love. Like the Mobius strip, the impossible heart seems to have no beginning or end. The decorative design can also be viewed as a braided or twisted heart.
Did you know? The heart as a symbol for love arose during the Middle Ages. The first use of the symbol may have been accidental. In a French manuscript entitled "Novel of the Pear," from the year 1250, is an illustration of a kneeling man handing what appears to be a heart to his love.
The heart, however, is actually a pear, the arches being formed by the overlap of the man's fingers. The artwork was influential nonetheless, and the scalloped and pointed heart symbol for romantic is still in use today, even as an emoji.
Would you like to draw an impossible heart? This easy, step-by-step heart drawing tutorial is here to show you how. All you will need is a marker, pencil, or pen, and a sheet of paper. You may also wish to color your finished drawing.
1. Begin by drawing a heart shape. Use a curved line to outline each side. Notice, though, that the top point of the heart is replaced by a short curved line. This shape outlines the interior of the impossible heart.
2. Extend a curved line from one arch of the heart. The line should run roughly parallel to the outline of the heart and extend past the bottom tip. This outlines the interior of one of the impossible heart's beams.
3. Extend a long curved line from the tip of the line drawn in the previous step. This line should be roughly parallel to the side of the heart, ending just about the point where the heart's arches meet. This outlines part of the impossible heart's beams.
4. Draw a long curved line extending from the edge of the heart's arch. The line should be roughly parallel to the first beam of the impossible heart. End the line parallel to the heart's bottom tip, and connect it to the tip using a short straight line. This completes the beam on this side of the heart.
5. Draw a short, straight, diagonal line extending downward from the heart's inner tip. From this, extend a long curved line upward to the side of the heart's upper arch.
6. From the inner side of the heart, extend a curved line upward. This line should curve with the flow of the heart but not attach.
7. From this line, draw a curved line to the top of the opposite arch. This line should intersect the other open line, fully enclosing the figure of the impossible heart.
8. Shade the impossible heart using straight horizontal lines of various lengths.
9. Complete the shading of the heart.
10. Color your impossible heart.

"The eyes are the window to the soul." So states an antiquated maxim. To scientists, however, the eyes are very interesting. For example, researchers are currently developing technology that could use patterns in the iris of the eye to identify people, much as the fingerprint is used currently. Movies and television have long depicted such technology, but it may soon become a reality. In fact, some airports are already testing this 'eye ID' technology.
To artists, the eyes hold another interest. The eyes are surrounded by many, many small muscles, and the movement of these muscles is an indicator of emotion on the human face. Our eyes, for instance, can show whether we are happy, sad, angry, frightened, excited, or bored.
The eyes, then, are an important means of expressing these emotions in the visual arts, yet many artists find the eyes to be one of the more difficult portions of the human face to capture accurately. What is more, it is almost paradoxical that the eyes are one member largely responsible for our ability to draw the eyes of another.
Almost every drawing or painting of humans or animals includes eyes, whether open or closed. As such, many styles have developed. The simplest eyes involve nothing more than a solidly shaded dot. Other simple eyes consists of a circle with a shaded dot inside it. The Japanese manga and anime art styles often lend straight lines and squared corners to the shape of the eye.
Would you like to draw a pair of eyes? Perhaps you are working on a portrait of a friend or family member. Now, the complicated task of drawing realistic human eyes is easy with the help of this simple, step-by-step drawing guide.
All you will need is a pencil, a piece of paper, and an eraser. You may also want to use crayons, colored pencils, markers, or paints to shade your finished drawing. Notice that each step of this drawing guide includes an illustration as well as explanatory text. New lines added in each picture are highlighted in blue.
