Core Animation

I have gone over the CA docs ... a quick read.

I have an iPhone app that uses the accelerometer to move a puck around the x,y plane. It filters out the effect of gravity per the sample code.

I would like to animate two background layers, one rotating cw the other ccw and use different CG blends based on the current location of the puck.

Do I need to make the animation in a separate thread or does CA handle that for me? I.e. I need responsiveness from the accelerometer and the visual effect of the rotating backgrounds/
