In order to change the cursor wou have to use the setCursor function or the setOverrideCursor in order to apply it to the application. You can construct any cursor you want using a QPixmap as constructor argument.
In order to achieve an animation effect you will need a QTimer. At every timer event you have to change the cursor's pixmap in order give the feel of animation.
