Script.aculo.us website relaunched: It's About The User Interface, Baby! Looking for the world like something designed with Flash, the new Script.aculo.us home page just begs you to study its underlying code. Those Wollzelle folks are just amazing, and this Prototype.js-based JavaScript library remains one of the premier Ajax/DHTML toolkits around. I really like their new tagline, too! I couldn't agree more.
