From the developer:
It lets you defined splines you can use for non linear interpolation in the framework. The editor actually uses the framework to play some effects.
Property ranges let you easily animate Swing components. For instance, you can ask the framework to change the background color of a JButton from blue to red over 400ms at 60fps. It's really great and better stuff are on their way.
