Dynamic Illusions |
Optical Illusions take on an extra dimension when they are animated. Sometimes the animation reveals the deception, perhaps by removing the elements that cause it, or by bringing in elements that allow a truer comparison. Sometimes the animation sharpens the illusion. See for yourself!
Moiré Patterns
Moir� fringes are an interference pattern that is formed when two similar grid-like patterns are superimposed. They create a pattern of their own that does not exist in either of the originals. The result is a series of fringe patterns that change shape when as the grids are moved relative to each other.
SVG Gallery
These animated optical illusions are written in SVG, the Scalable Vector Language from the W3C. You will need an SVG viewer; try the Adobe SVG Viewer.

PHYS 101 Light and Visual Phenomena
by Michael J. Ruiz, Dept. of Physics, UNCA. The program consists of a number of interesting optical illusions that will display on your screen. This could be of interest to teachers for use in a classroom, to parents for their kids, or just for us big kids ourselves.
