Rubberduck’s Screenweaver MX.
The beta testing is over: Screenweaver MX commercial version has been released today by Rubberduck, the Netherlands-based company that developed it, and the creators of Flashcomponents.net. Screenweaver MX is an extension to the Macromedia Flash player that provides Flash MX developers with a framework to produce rich media desktop applications, using their existing knowledge of the Flash platform and extending it to new applications. A free trial version is available for download.
Screenweaver is not like many of the Flash add-ons out there, it helps with the creation of fully functional rich-media desktop applications, that take advantage of almost every aspect of the Windows environment. I had the opportunity of participating in the beta testing and got to see the coolest things developed thanks to Screenweaver, but I agree with many others in the coolest of all: Screenweaver MX itself.
