4 boxes

These are four boxes. They are standing two by two next to each other. So far it is correct. It is also correct that each box has outer corners. The boxes are not tied together with each other. The front most box is standing a little bit in front of the other boxes so that they form a connection to each other. In this way they become related to each other. Because of this overlap there are interesting geometric forms created between the boxes: triangles and trapezoids.

If we look more carefully to each box is it obvious that each box is an impossible figure. The viewer will normally inspect all four boxes before it is possible to make the conclusion that they are all impossible figures. To do this is it necessary to follow the internal structure of each box with the eyes. When doing this the viewer will register the various color transitions. When looking at the shapes and the colors the viewer will start to figure out the logic behind the color scheme. There is logic in the color scheme broken by irrational choices of color. Each box has another pattern. There is one infinite box. Three boxes have two ends. One box has an internal loop.
