imothep85 , sorry, I wasn't clear, the diamonds rotate the same as the ring, the inverted Y axis that I am talking about is regarding how they move around the canvas when the mouse is moving.
Moving the mouse right/left make the diamonds move right/left. However, moving the mouse up/down makes the diamonds move down/up, the movement is inverted.
And if you move the mouse on the center of the ring the diamonds stay in position (which I am sure you already know about)
