OK, after some experimenation and reading of the android source, I've learned a little... First, it appears that I don't necessarily have to worry about creating different gestures in my gesture library to cover different angular rotations or directions (clockwise/counterclockwise) of my circular gesture. By default, a GestureStore uses a sequence type of SEQUENCE_SENSITIVE (meaning that the starting point and ending points matter), and an orientation style of ORIENTATION_SENSITIVE (meaning that the rotational angle matters). However, these defaults can be overridden with 'setOrientationStyle(ORIENTATION_INVARIANT)' and setSequenceType(SEQUENCE_INVARIANT).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
