Flow

The Musee du Orsay was constructed inside of an old train station. The above image is of one of the walkways that traveled the width of the building. The lights behind the frosted glass are embedded in the bridges that circulate the patrons to the museum. It seemed to me that the importance of those lights were to give a sense of how the building works, not necessarily to illuminate a pathway. They draw your eyes from one end to the other. It establishes flow, an architectural decision. Also, as people walk along the bridges their shadows can be seen from behind the glass.
