alot of what has been developed has been great but lacks on the design side. I'd love to be able to help out with a new media player UI, or a flash game application, or any other interesting projects you guys have.

I bet if you posted a few mockups of design ideas, a lot more people would be interested : )

You can freely participate in http://tabletui.wordpress.com blog to show your UI ideas. As you can see, many of them can be released and actually ARE released
You're very welcome!
