• Fast and easy to implement (perfect for ajax applications).
• Don't need to spend time in an image editor creating gif animations.
• Very flexible by multiple (optional) parameters for individual styles.
• Get always a proper loading indicator independently of parent elements style.
• Includes a bunch of (built in) shape designs.
• Moves the DOM tree up to find the next parent block-level element.
• Freezes the parent element visual (overlay) and technical (mouse events).
• Works with html elements even if (moz/webkit)-border-radius is activated.
• It's dead easy to add or remove the loading indicator to/from an html element.
• Free of charge use on non-commercial and private web sites.

In older browsers, the script degrades to simple quadratic shapes.
