Tour de Flex is an application for exploring Flex capabilities and resources, including the core Flex components, Adobe AIR, data integration, and a variety of third-party components, effects, skins, and more.
A Flex component similar to the many "spinner.gif"s that are used on Web 2.0 pages. This is a sort of indeterminate progress indicator that can be used to demonstrate to the user that something is happening.
