Default Xorg cursor set with few missing cursors added (zoom-in/zoom-out cursors...) and with few little changes: e.g "hand" cursor (it's visible when clicking links) is also in black color now and "watch" cursor is visible as animated colored ball (it was tacken from "Shere Khan X" cursor theme). To install it, just copy "X11-Default-Black" dir to /usr/share/icons. If you're using simple WM without GUI settings, then add "Xcursor.theme: X11-Default-Black" to ~/.Xresources (also add "xrdb -merge ~/.Xresources" to your WM autostart script). To use this cursor theme in GTK apps, add "X11-Default-Black" to "gtk-cursor-theme-name" line in ~/.gtkrc-2.0 and ~/.config/gtk-3.0/settings.ini files, or choose it via some GUI GTK settings application (e.g lxappearance).
