This revolutionary component really turns the tables for Vaadin. It lets you make the world go around.
The Revolver component displays an image resource and allows you to rotate it by dragging it around with mouse. The rotation change can be listened for and you can also set the rotation programmatically.
Tested on Firefox and Chrome. Possibly doesn't work on IE.
Known issue: The component theme doesn't work properly, so set the component as "overflow: hidden" in your theme to avoid scrollbars from appearing.
