JavaScript

var ticker = $('div.ticker'),
    tickerInner = ticker.find('.ticker-inner'),
    tickerHeight = ticker.height(),
    tickerDelay = 1000,
    tickerSpeed = 15000,
    tickerInterval;

tickerInterval = setInterval(function(){     
    tickerInner.animate({'left' : '-='+1024}, tickerSpeed, function(){ // Animate top -= the height of the ticker
        $(this).find('p').first().appendTo(tickerInner); // Move the top, hidden p to the bottom
        tickerInner.css('top', 0); // This isn't totally necessary, I just like to keep my animation numbers low
    });
}, tickerDelay); // Call this every 3000ms

// Need to stop the ticker?
// clearInterval(tickerInterval);
