Free xcursor software for linux

Silver XCursors 3D provides the same animated cursors as in my Golden Xcursors 3D theme, but this time rendered in Silver.
Installation:
Copy the two folders Silver and default to your ~/.icons directory and
restart your X-Server.
If you want to have bigger cursors, you have to create an .Xdefaults file
in your home directory and insert the following two lines:
Xcursor.theme: Silver
Xcursor.size: 48
The default size is 32.
Thats it!
Note: If the animations are flickering on your nvidia card with the latest
driver, add the following line to your XF86Config file, into the nvidia
device section, to fix it:
Option "HWCursor" "off"
Enhancements:
- added pirate
- a little less animation (requested)

XCurs is a program used for editing XCursor formatted XFree86 mouse cursors. This type of format became available as a result of Keith Packards work on XFree86 v4.3.
Whats So Important about xcursor?
xcursor contains a) Alpha Info, b) ~16 million colors c) animation of cursor, none of which were available in prior cursor incarnation (bitmap cursor format, which had transparency, but not colored one and only 2 colors which were not quite easily changeable.)
Main features:
- loading (from RGBA capable files)
- saving (no symlinked cursors will be saved) (into XCursor format)
- xhot/yhot/delay management
- removing of single image
