1. A method of specifying a choreographed media production as a graph of nodes and acyclic directed paths defining related sets of forward and reverse traversals comprising the steps of:

  • (b) adding to the graph a leaf node with a data-generation function that generates in a reverse traversal data related to the choreographed media production based on a temporal context;

    (c) adding to the graph an intermediate node with a temporal transform that takes a temporal context as an input and derives a new temporal context as the output, during a forward traversal, and then restores the forward traversal'"'"'s input temporal context during the corresponding reverse traversal; and

    (d) connecting the intermediate node into the graph with a directed path that defines both a forward traversal that carries a temporal context from the root node through the intermediate node to the leaf node and a symmetric reverse traversal that begins when the forward traversal is completed and ends at the root node;

    wherein the root node defines both a spatial context and temporal context, the intermediate node includes the ability to apply a spatial transform during forward traversal and reverse this spatial transform during reverse traversal, and the leaf node bases its data-generation function on both the spatial context and temporal context.
