Graphics to show progress in AJAX+PHP?

[digitman]

Are there any free graphics that I can use to show progress when an AJAX request is being sent to a PHP script in my HTML files? I want to use that one with changing lights, but don't know its URL and wether or not its free (and not copyrighted, etc). Anyone got any links?

Why don't you write it yourself?
