Re: How do I rotate an image?

CATransform3D would be the correct way to do what you want. Simply 
create your transform with CATransform3DMakeRotation, and apply it to 
your layer by setting your layer's transform property.

The only issue I've run into is that the transform doesn't look 3D. 
I.E. it doesn't have that nice perspective look that the dock has. 
Instead, the image just has a squashed look. If anyone has any 
solution or flag that needs to be thrown to accomplish a nice 
perspective transform, I'd be interested in knowing about it....
