D Grid

The other day I finally took care of the Optical Illusion to the left of the D in my personal logo. The balance of the mark is much better now. - Optical illusions are often described as visual images that differ from reality - the eyes and brain 'sees' something that doesn't quite match the physical measurement of the image. Optical illusions can work in various ways, they can be images that are different from the objects that make them, they can be ones that come from the effects on the eyes and brain through excessive stimulation, and others where the eye and brain make unconscious inferences.
