That's cool - when I used PNGs and rotated them, they looked all aliased on
the iPhone so I went with CAShapeLayers instead. Thanks for that link
though.

SampleCode, there is an example of using a dial created with Core Animation.

My rootLayer was using the view's bounds, etc. so this works now:
rootLayer = [CALayer layer];
rootLayer.frame = CGRectMake(240, 160, 240, 160) ;*//self.view.bounds;*
[self.view.layer addSublayer:rootLayer];
boxPath = CGPathCreateMutable();
CGPoint center = CGPointMake(0,0);*//self.view.cente

Will do. One question - when I am rotating around z - it's using the top
left of the shapeLayer as the anchor point. Trying to set it differently
isn't changing the anchor point...

Yes, please brush up on Core Animation. You can apply arbitrary
transformations to a layer, or you can use the rotation/position
prop
Cool - thanks for that heads up.
If I use CAShapeLayer, can I use CGAffineTransform on it? I need to pour
through the docs now I guess.

Yes, use vector-based drawing with CAShapeLayer.

I have 2 UIImageView, each containing a PNG (about 2 pixels wide for the
images). When I rotate these around, the edges of the PNGs look terrible and
I was trying to get MORE anti-aliasing to happen to smooth out the jaggies.
hourHand.layer.anchorPoint = CGPointMake( 0.0, 0.9 );
