One idea that James Padolsey suggested [4] was to allow people to define custom corner shapes, perhaps by cubic beziers. I think it’s a good idea, perhaps if we re-use the existing cubic-bezier() [5] notation from transitions and move it to css4-values as a new value type.

Thanks for creating that, Lea. For values like border-radius:50%, the fallback seems so very different from the 'scoop' shape that it doesn't seem appropriate. Maybe this should not be tied to border-radius, but just be a new property that overrides border-radius completely, providing both radius and shape together.
