No, it won't track like Terminator.  Terminator didn't use a light gun.  It used a joystick to play the game, it was just disguised as a light gun.  The terminator gun was nothing more than a large joystick with a plastic housing. 
 I think most of use here are quite aware of how The original 
Terminator gun worked...
I really wouldn't care if it was a joystick, keyboard, mouse,
whatever, as long as it looked like a gun acted liked a gun; 
and worked with more than just 2 games.
I think what we would like to see however is a solution 
that would work with all games regardless! 
As I stated before, Light Guns can only track like that if you have a very bright (ie white) screen.  If you put up a white background, a light gun can track the movement of the gun, however, when you hit a black area on the screen, it will not be able to track.
 You know I heard a lot of people complain about the flashing
of the ACT Lab Guns.. I really don't mind it at all If I can find 
a solution that will track and support more than 2 games.. 

 A Well I had hoped... 
guess I'll just hold off for something else
