Welcome to the most comprehensive collection of optical and sensory illusions on the world-wide web. This award-winning collection consists of innumerable interactive demonstrations, up-to-date and reliable scientific explanations, school projects, illusion artwork, interactive puzzles, 3D graphics, suggested reading lists, bibliographies, perception links, and much more. There is literally hours and hours of fun and cool material here! Most of the effects, demonstrations, and artwork appear here for the first time. We hope that you will agree that this site is what the web was best suited for!
To benefit the many diverse visitors (over 4000+ separate users a day on average!) we have decided to make two sites (containing more or less the same material), although the level of explanations will be different.
Introductory Level. This level contains all the material, but with explanations that are easily understood. This level contains an added section on recommended school science projects.
Advanced Level. This level contains the same material, but the level of scientific explanations is much more rigorous (at the level of Scientific American). The explanations are more in depth. This level is best for the serious student or researcher.
All sections are best viewed with Netscape 3.0, Communicator 4.0 or Microsoft Explorer 3.0. We cannot guarantee that this site will work or display properly with other browsers.
This is a Frames enabled site. Most interactive demonstrations require a Java plug-in to be enabled. The interactive puzzles and auditory illusion require a Shockwave plug-in.
