OK, fiddled around a bit with the rim concept but code was getting a bit too complex (I am trying to KISS per the concept of an easy port to WP7) so I have put ot on hold until we see what is around the corner.
Thanks for the great feedback..
lagg in movement.
on my tx2 the object is always moving to slow.
also it jumps.... due to the way you are trying to use the handle it seems to move in an odd way to me.
also you need to have it work with the display better. when i go to rotate the display it does not fit. it's not scaling or resizing to adjust.
