If you are able to do this with images, perhaps you can keep all of your controls in an NSView object (as usual), and then render the NSView into a bitmap image using cacheDisplayInRect:toBitmapImageRep: just prior to executing the flip effect. The steps would be:

2. Display that bitmap in a layer suitable for the flip effect
3. Hide the NSView and expose the image layer
4. Perform the flip effect
