Those of us that love kinetic sculpture always spend hours mesmerized by rolling ball machines. If memory serves me correctly the first one I saw was the George Rhoads installation at Logan Airport in Boston. Imagine if you could view a rolling ball machine from ball's eye view! It was that thought that made me love this video shared by SwissMiss from Laughing Squid
The route of a bag from your hands at an airport and back into your hands at your destination is much like being the ball in a roling ball machine. And Delta made a video of it using six cameras installed in a suitcase. Fun to watch!
