radial-gradients

I would like to animate a radial gradient to shrink and grow the inner radius, as if it were pulsing.

Right now I'm rendering the gradient with CGGradient, but I'm not sure how to animate it. I've seen this topic

http://stackoverflow.com/questions/1819311/can-you-animate-gradients-using-quartz-in-an-iphone

Which explains how animate a linear gradient with CAGradientLayer, but it doesn't seem like this will draw a radial gradient.

Is there an easy way to animate a CGGradient, or some way to create a radial gradient CAGradientLayer?

Any thoughts are appreciated.
