[re-posting from the correct account]   Great work, Blake! This sparked me to look for a way to just define an ease that'll do all this wizardry for you and here's what I came up with:    var ExpoScaleEase = function(start, end) {         var factor = Math.log(end/start),             change = end - start;     return function(v) {         return (start * Math.exp(factor * v) - start) / change;     }; }; //to use it, you pass in the start/end scales... TweenLite.to("#img", 5, {s
