Some thoughts on impossible figures.
Based on an artistic analysis of the construction of "impossible figures," their structure and the origin of the perceptual effects they induce are discussed, including the use of a basic indeterminate space of intersection, penetration of indeterminate solids, and symmetry. These and other points are illustrated by 17 progressively more complex figures constructed by the author.
