Dushkin worked within this framework and very tight construction schedule (half a year from earth pit to completion). Later, in 1973, he summarized the experience: "Optical illusion is worthless. Under ground, light is the most vital structural element that livens up materials and underscores shapes...
As touched upon above, the House sculptures actively employ optical illusion. Specifically, Lichtenstein's exploration of perspective in the House series reflects the principles of illusion discussed in the guidebook Drawing by Seeing, written by Hoyt L. Sherman, former professor at the Ohio State University School of Fine Arts.
An isometric illusion (also called an ambiguous figure or inside/outside illusion) is a type of optical illusion, specifically one due to multistable perception. Jastrow illusion The Jastrow illusion is an optical illusion discovered by the American psychologist Joseph Jastrow in 1889.

He also wrote multiple books on the topic of optical illusions. Felice Varini's 2014 work Three Ellipses for Three Locks in Hasselt, Belgium is an image of three loops that are made up of segments painted on to over 100 buildings. It is only visible from a specific vantage point over the city. [13]
The word we apply to the design principle is used by the Roman architectural historian Vitruvius, [1] and derives from the Greek word έντείνω (enteino), "to stretch or strain tight". Creating the illusion of greater strength or perception of height may have been an objective in the application of entasis.
The use of negative space is a key element of artistic composition. The Japanese word "ma" is sometimes used for this concept, for example in garden design. [2] [3] [4] In a composition, the positive space has the more visual weight while the surrounding space - that is less visually important is seen as the negative space.
