jQuery Impromptu is an extention to help provide a more pleasant way to spontaneously prompt a user for input. More or less this is a great replacement for an alert, prompt, and confirm. Not only does it replace these but it also allows for creating forms within these controls. This is not intended to be a modal replacement, just a quick tool to prompt user input in a fashionable way.
Although it is not an alternative for modal windows, it can display any HTML content, supports sequential messages & more.

The plugin comes with a bunch of options for maximum customization like:
- loaded, callback & submit functions to step in every point
- changing prompt & overlay speeds
- using different animations on prompt windows 6 more
The look/feel of the message boxes can be updated easily via CSS & various examples are provided on theming.
