A "path-enhanced" presentation is automatically generated from previously recorded "path-enhanced" multimedia based on time and location information associated with the multimedia. The path based on the time and location information is rendered over a two-dimensional map. The presentation indicates position and progress along the path, and at the same time, previously recorded multimedia corresponding to points or segments of that path are automatically played. When the moving icon reaches a location that is associated with multimedia, that multimedia is automatically played.
