Phi Cont'd

Students,
Here's one more example of the Phi phenomenon, which I made up just now. It shows Elvis Presley in two successive positions, with the illusion of motion. The other animated gif I made up, of two autumnal scenes, does not have the same illusion of motion, since the images are too different to create an illusion. Note that in the Elvis gif neither the slow speed nor the disontinuity of sequential images would allow persistence of vision to create the illusion of motion; this is achieved by the Phi (a psychological) phenomenon. I've also included a sample of a flip (flick) book (see attached video). Finally, for those who wish to explore flip books further, there are many web pages that include them.
