From a development point of view it's of course interesting, indeed from a user side of view it's challenging to make it intuitive. You might use two fingers to control the angle of the magnifying glass, or the dragging direction controls the angle. For
example the glass is always in front of the dragging direction, this could work intuitive enough, and just average the last few coordinates so it's not too jumpy.
Greetings from a fellow Silverlight programmer,
Interesting and quite reasonable, but it would also move it away from the KISS principal, which for now I want to retain (considering I will probably have to rewrite once we know the details of the WinFon7 SDK!)
