Globally hide mouse cursor in Cocoa/Carbon?

Question

Is there a way to globally hide the mouse cursor for all apps in Cocoa (or Carbon)? Or at least replace it with something else?

EDIT: Thanks for the input guys, but turn

Check out: http://developer.apple.com/legacy/mac/library/samplecode/CarbonCocoa_PictureCursor/listing2.html It's an old sample, but probably still works.

I expect that you're going to be limited to your application window, however. If you want to hide it for everyone you will probably have to make your window cover the screen.

Fun fact: The old toolbox function was simply "HideCursor()".
