how to do this?
2) I also have no idea how to figure if, once the screen saver is
on, how to stop if when something happens (mouse move, key stroke,
mouse click). I've looked at the docs for NSView and there doesn't
seem to be any methods that would make this easy. What can I do here?
If you are going to write a screen saver, you will need to get
support from the window system (X11, if you're just targeting that).
The GNUstep framework won't help you with system-wide event
handling. I'd recommend looking at other screen-saver
implementations, such as the GNOME screensaver (which is probably the
most rigorous one written - although it's hard to follow, it has a
very good philosophy), and also the basic xscreensaver. You also need
to be very aware of the security issues surround screen savers and
password handling (if you implement that).
