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?

+1  A: 

I just looked at it, and it looks a bit too complex to do with a single image and some sort of UIView animation. I'd just bite the bullet and use a set of images for it -- the total footprint can't be very much.

It's a beautiful animation though, isn't it?
