Perception puzzles, Visual Perception, Optical illusions and Paradoxes

The components of an object can distort the perception of the complete object. Our mind is the final arbiter of truth. Most optical illusions are the result of 1) incongruent design elements at opposite ends of parallel lines, 2) influence of background patterns on the overall design, 3) adjustment of our perception at the boundaries of areas of high contrast, 4) afterimages resulting from eye movements or from kinetic displays, or 5) inability to interpret the spatial structure of an object from the context provided by the picture.

If there’s one thing I am grateful for — and it sure isn’t the pay — it’s that my work has allowed endless time to hone my craft to Louis Skolnick levels of grammar geekery. As someone who slings red ink for a living, let me tell you: grammar is an ultra-micro component in the larger picture; it lies somewhere in the final steps of the editing trail; and as such it’s an overrated quasi-irrelevancy in the creative process, perpetuated into importance primarily by bitter nerds who accumulate tweed jackets and crippling inferiority complexes.
