The human visual systems receives constantly a large amount of information that has to be filtered if we want it to be meaningful. A key element to know where to direct our attention is a classification between figure and ground. However, that separation is not always evident. Examples as Rubin's vase show that is possible to create images that have more than one stable interpretation. But, can the same type of ambiguities be created on a sequence of moving images?. Are we able to track what is happening at the local and global scale? "Background singer" is a short animation that explores these questions and the possibilities of parallel story telling using the duality of local and global.
