Nth Screen / Nth Camera is a platform for respectively playing and recording collections of synchronised videos across mobile phones and tablets. Running against the trend for us to communicate remotely, these multi-device, multi-segment, multi-viewpoint films are principally for us to create, enjoy and discuss together in social, co-located groups. We encourage experimental films for collective witness, documentary, humour, drama and poetry. In this talk we will demonstrate taking a 'groupie' (selfies were yesterday), and show examples of Nth Screen films, including the song and flight of birds across mobile phones.
