Refresh burst animation

I really enjoy Apple's take on pull to refresh. However, I feel they could have maintained their metaphor slightly better. They use a refresh arrow in the bubble only to replace it by a spinner once it's refreshing.

This animation tweak makes the bubble burst when it hits the navigation bar, setting loose the arrow which starts to spin. When it's finished refreshing it goes down the drain.

Be sure to watch the attached movie for 1:1, 60 fps glory.
