        app;

    rand = function( arr ){
        return arr[ ~~(Math.random()*arr.length) ];
    };
    //draw an image using the canvas2d API    
    generator = function( canvas, next ){
        var ctx = canvas.getContext('2d');
        ctx.fillStyle = rand(['aquamarine','teal','red','yellow','lime']);
        var border = 8,
            sqSize = canvas.width - (border*2);
        ctx.fillRect( border, border, sqSize, sqSize );
        next();
    };
	//start a connect server that servers the generative /favicon.ico
    app = connect()
        .use(faviconCanvas( generator ))
        .use(faviconCanvas( generator, {
            route: '/apple-touch-icon-precomposed.png',
            size: 152
        }))
        .use(function( req, res ){

        })
