Registering in a website sometimes becomes annoying, especially if the website is a very simple service like bit.ly.
The Gravity Registration plugin tries to solve this, by creating a registration form that “pops out” the next required field
The plugin is obviously great for simple services, and services for the masses, where no personal information except e-mail is necessary.
You can add new fields and spice up the design with CSS.
Just don’t remember to stick to as few fields as humanly possible. ;) No one likes dozens of new fields to fill flying at them.

The above pictures illustrate the concept — once a user fills a box with text, it automatically resizes to a larger one.
