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.

progress bar is over a Libre Office tile in the middle of the
Launcher)


Cheers, chr
