Creating the Iphone MapKit showUserLocation Ring Annimation

Anyone know how of an approach to re-create the animation that mapkit uses on the showUserLocation ? Would you do it with a series of images or a single image that is then expanded and faded out?

I just looked at it, and it looks a bit too complex to do with a single image and some sort of UIView animation.

What is the best way to download image data from ASP.NET to iphone?
I'd just bite the bullet and use a set of images for it -- the total footprint can't be very much.

Not sure how Apple does it exactly but I know they're using 3 differently sized images for their halo animation.

Probably because scaling the largest image to a small size would result in artifacts..
