We are glad you are interested in our products.
Currently we do not cover-flow UI for WinForms. We offer something similar, however - our RadCarousel control can loop images and UI pieces around in a simulated 3D view. The path of the items can be defined by an ellipse or Bezier-curve. For more information you can look at these pages:
We do have a cover-flow in our WPF suite though, which will be released next week.
