Motion of People over Time

This short animation is a representation of people moving over the course of two minutes.  The two sets of spheres (black and red) represent the individual movement of people over time (black to white in the mirror and black to red in the camera frame).  As the Black go to white they are visible in the mirror, when they are black they are not in visible in the mirror.  The Red represent people who are present in the camera frame; so as they go to black they are leaving the frame and are no longer viewable.  There is also an attempt to capture the proximity of the people as they are close to the mirrors and also close to the camera in frame.  The interesting point that this animation shows is location over time where the individuals are not visible in the mirror and also not visible in the camera; this is represented by the areas of only black spheres.
