Silverlight VisualBrush and rounded corners

As you know Silverlight 3 doesn’t support VisualBrush, which can make things like this pretty tricky. Here’s my attempt at a workaround It’s a control called VisualImage which can be pointed at any element and exposes it as a WriteableBitmap. You could bind an Image to this to create a reflection effect, or use it to apply clipped, rounded corners to anything!
