Synergy of graphic architecture and design either buildings or close up details. Computer altered to create conceptual optical illusion designs of patterns, and repetition of forms and shapes.

For other examples you can also look in the "Abstract - Symmetry of Smoke and Mirror Images" Gallery.

One of the most well known optical illusions is known as "Rubin's Vase" this simple illusion devised by Danish psychologist Edgar Rubin can be perceived as both a vase or as the profiles of two human faces gazing at one

The visual effect generally presents the viewer with two shape interpretations, each of which is consistent with the retinal image, but only one of which can be maintained at a given moment.

The distinction is exploited by devising an ambiguous picture, whose contours match seamlessly the contours of another picture sometimes the same picture.This was a practice M. C. Escher used in some of this pictures.

These stimuli provide an excellent and intuitive demonstration of the figure-ground distinction the brain makes during visual perception, since it involved higher-level cognitive pattern matching, in which the overall picture determines its mental interpretation,
