Here a quick Flash (booo) prototype showing the connection that we could have between the knight rider bar and the progress of the process. Every time the process progresses it could send a pulse event to the bar (emulated in the prototype by a click on the "pulse" button). There is a maxmium speed the bar can reach and if there is no activity the bar slows down until it stops.
