Abstract: A system for creating an output comprises a processing unit, a user input module operably connected to the processing unit, and a video monitor operably connected to the processing unit. The processing unit provides on the video monitor: a grid image comprising multiple cells, each cell representing a duration of time; and a selection area comprising multiple select icons, each select icon representing a source data file. The processing unit is configured such that a user can create a grid layout representing the correlation between individual selected source data files and one or more of the multiple cells. The processing unit produces the output based on the correlation.
