Reverse Mouse Cursor

Any software/tweak/utility available to change the appearance of the mouse cursor so that it's reversed (or mirror image)?

Have my mouse setup as lefty, so looking to change pointer direction of my cursor.

Thanks in advance for any input!

Unsanity's Mighty Mouse can do it. It's not yet been updated for Leopard though.

Has anyone found anything to do this yet? I also am a lefty looking to have the arrow pointing to the right. I have searched the web and found nothing. I am actually considering returning my new Mac because of this.
Thanks!
