Control the view with mouse move (no clicking)?

Hi everybody

Is it possible to control the view without clicking? I was thinking of something like mouse_move -> when the mouse is close to the center of the 'area', the view is still. When it is moving towards the edges, the rotation changes (and accelerates depending how close the mouse is to the edges).
I am sure this can be achieved but I have honestly no idea how. Thanks a lot for the feedback!

Oh, I have just found this: http://www.krpano.com/forum/wbb/inde…ead&postID=2072 Looks good, will check it out!
