1. A navigational device, comprising:

  • a processor;

    a memory in communication with the processor;

    a display in communication with the processor;

    wherein the device dynamically generates a route path using the processor and the memory from a moveable location associated with the device to a destination of the device by repetitively dynamically expanding one or more adjacent locations and inserting the adjacent locations into a first data structure wherein one or more first locations of the first data structure are associated with a then existing least cost location in the route path, the route path is dynamically generated from the moveable location, the first locations of the first data structure, and the destination; and

    wherein at least a portion of the route path is dynamically communicated to the display.
