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).
