Well done, Telerik
If you haven’t seen Telerik’s Windows 8 controls, you should check it out. Just go to telerik.com and install the trial and then open the demo app (there’s one for HTML/JS and one for XAML/C#) in Visual Studio and launch it.
Their presentation is awesome and the controls themselves are way cool. They’re simple and clean and have just the right amount of animation – enough to make them look alive but not so much they look brassy.
