Although the look of Gnome cursors is quite good and attractive, now we can modify it and enjoy different themes.
The cursors are named according to the freedesktop.org cursor naming convention, compatibility and hash cursor names are linked.
In addition to the original cursor pack left-handed and opaque versions are still available here.
It includes cursors of 3 different sizes, in two styles and six different colours. That means it will suit your needs for sure.
