Yes the bitmaps are different, not only the angle changes (there is also some kind of reflection effect on it and patterns). So rotating the same image (which I guess is your suggestion) won't do the trick here. I am also thinking about using the same fade in fade out effect on another animation where a glowing bowl appears and hides in a a kind of slow 'puls rythm' - here also the bitmaps are different and it won't do with hiding in&out the same bitmap....
