Can anyone on this list recommend a video for demonstrating basic motion phenomena to an undergraduate perception class i.e., structure from motion, apparent motion, etc.? (I have these on CDs. A video would be a lot easier.) Thank you! Faith Florer Adjunct Asst. Professor TSOA and SPCS, NYU and Psychology Dept., Marymount College http://www.river.org/~flf/Faith.html
