Progressively masking password inputs with jQuery

Today alistapart published an interesting article on password masking and whether or not it was time to give it up. They also proposed an iPhone-like progressive masking behavior and wrote an example implementation in javascript. I liked the idea and tried to come up with a way I could use this in my existing projects, which are usually built using jQuery. This is my quick and dirty take on it. It might also make a good plugin some day. Use it in your own projects if you like it. Sample Page using jQuery
