Does ssh put in a layer to intercept X calls?

How does X know where to display (i.e. if both boxen are
running "X," which one displays the invocation of "xeyes"
(or whatever))?  Surely an ssh tunnel doesn't take over
ALL X & redirect it to the remote server?

True enough; any X11-displaying program merely needs *some* X server
to display onto.  It doesn't care if that's local or via the net.
