A nice-ish effect that looks a bit like when someone's typing

typingEffect.js

var typingEffect = function(string,node,delay){
    var splitString = string.split(""),
        increment = 0;
    var le_interval = setInterval(function(){
        if (increment < splitString.length) {
            var span = document.createElement("span");
            span.innerHTML = splitString[increment];
            node.appendChild(span);
            ++increment;
        } else {
            console.log("finished typingEffect() on " + string + " at " + node.toString());
            clearInterval(le_interval);
        }
    },delay);
}
