Hide the cursor from the terminal
so what i just did was to download cursorcerer pref pane.  then i unzipped it.  then showed package contents.  then simply double clicked the resource called cursorcerer.app.  now my cursor is invisible -- even after moving.  so you could call this app from the terminal.  quite debilitating in my environment, but could be very helpful in others!

i was able to get my cursor back by running the preference pane.
