1. A wearable or portable lighting device for playing out, together with a plurality of other wearable or portable lighting devices, a predetermined time-varying lighting pattern over a space occupied by said device and the other devices; said device comprising:
at least one light source; memory for storing a representation of the time-varying lighting pattern; and at least one controller configured to determine a first current location of said device, to receive a timing signal for determining a current stage of the time-varying lighting pattern in synchronization with the other devices, and based on said determination and said timing signal, with reference to the representation in memory, to select a portion of the time-varying lighting pattern corresponding to the first current location and stage and to cause the at least one light source to play-out said portion.
