This demonstration of Magni-phi,  developed by Filip J. Pizlo, requires a Java 1.1 browser, such as Netscape 4.06 or later and Internet Explorer 4.0 or later. Magni-phi is a greatly enhanced version of the phi-phenomenon Max Wertheimer discovered in 1912. It is a "pure" movement because the objects creating the percept, the disks, are not seen to change position in space. A number of options are provided.

ARVO Demo was displayed during the talk given by Steinman, Pizlo & Pizlo at ARVO on Monday, May 1, 2000 @ 15:45 GMT. This demo provides a series of pre-configured menu options that demonstrate the robustness of Magni-phi, and compare it to Phi and Beta.

Custom Magni-phi is user-configurable. Magni-phi depends primarily on delay parameters, so it is best to leave them alone until the other options have been explored.

Custom Simpli-phi demonstrates Wertheimer's Phi, which is much less vivid.
