tested only under windows 98

Installation:

open: 
 windows explorer / control panel / mouse
select tab page: Pointers

now you can setup by pointing to the path where you extracted/installed this package, I suggest c:\anicursors

Animated Cursors with transparent hotspot are the files THs_*.ani
This is intended to you be able to see where you will be clicking in case these animated cursors are running.
Despite THs_rocket.gif have no use to transparent hotspot, it is more cool to keep that area clean to the .gif file usage at homepages etc :)
