Audiotool - Making Music on the Web

So I stumbled across this site a few years ago. It's called Audiotool and it's basically a Music Making Site built on the web. It runs via Flash (I've hear from the devs they're switching to HTML5 soon), it has load of tools, a pretty big sample library, and the best part is it's completely free. It kind of makes me wonder what other kinds of services and products like this are on the web. Sure it's never as robust or extensive as FL Studio or Abelton Live, but for a web application, it's pretty impressive.

Just wanted to share!
