There is a reason that I recommend the Preferences method instead of
the Intuition "SetPointer" command.
	The SetPointer command changes the mouse pointer image only
in the window that you specify.  While you could repeatedly call
SetPointer for every window existing in the system, if someone were
to click outside of any window, I believe the original pointer image
would return.
	On the other hand, Preferences is global, and if you change
the pointer image with the SetPrefs command, the mouse pointer will
be your new image in EVERY window of EVERY screen on the system.
For many folks, this is an extremely bad thing to do, as other tasks
will look funny with the wrong pointer.
	Please recall, however, that for the application that was
originally mentioned (a demo that takes over the system) the
SetPrefs is a well-behaved command that will function even if Intuition
windows are not being used.  (Whether it will work if you CloseLibrary
intuition is something that I don't know...).

Lastly, and here I repeat Chuck McManis, if you only want the pointer
to change for your window, be well behaved and use SetPointer.
