Yes, Apple demoed this at WWDC but I think the interpolation technique I use is rather neat and allows you to easily adjust the layout and behavior of the layout.
CInterpolator objects are a little like CAKeyFrameAnimation objects except they're not necessarily time based. You can use them for (linear) key frame interpolation between any keys and values
- The "Gloom" layer doesn't do a very good job with alpha backgrounds.
- Aliasing is very obvious on straight edges when rotation.
- Test on low end hardware.
