2 -- Others

There are various impossible diagrams besides those stated above. There will be significant developments in these fields in the future.

New expressions will be created in the field of modeling when a new method to express "sight" is discovered. Moreover, the development of the expressions are strongly demanded because they contain strength and humor.

Several examples below will be briefly explained. There are two art works on reversal of a shape and its background. The work in Figure 377 has an equivalent content with that shown on the previous page. In addition, it is also a work which accompanies a reversal action between the shape and its background for sight recognition. Because it is easily understood using short legs, it is desirable to draw legs which are longer than a certain length. The art in Figure 378 is possible if it is seen in part. However, rolling the paper as a whole like this is impossible.

A diagram which is composed of two rectangles drawn using perspective is shown in Figure 380. Two square frames are placed directed toward a further direction with a sense of depth. However, it is difficult to judge what kind of special configurations these frames have since there is a trick at the connection in the center. That is an interesting point.
