function ScreenSaver(settings){     

	    this.settings = settings;     
	    
	    this.nTimeout = this.settings.timeout;     
	                 
	    document.body.screenSaver = this;     
	    // link in to body events     
	    document.body.onmousemove = ScreenSaver.prototype.onevent;     
	    document.body.onmousedown = ScreenSaver.prototype.onevent;     
	    document.body.onkeydown = ScreenSaver.prototype.onevent;     
	    document.body.onkeypress = ScreenSaver.prototype.onevent;     
	         
	    var pThis = this;     
	    var f = function(){pThis.timeout();}     
	    this.timerID = window.setTimeout(f, this.nTimeout);     
	}     
	ScreenSaver.prototype.timeout = function(){     
	    if ( !this.saver ){
	        window.location = 'www.baidu.com';
