Thanks! I must have glossed over that in the screensaverview
reference. :o)
Based on the documentation I assume then that it is possible to grab
a bitmap of the screen(s) before the screen saver blanks, and
possibly while it is running. What is the best way to do this? Can I
just call [[self superview] cacheDisplayInRect:[self bounds]
toBitmapImageRep:myBitmap], or is that too easy?

performGammaFade
+(BOOL)performGammaFade
Indicates whether the screen saver application should perform a
gradual screen fade when it starts and stops the animation. This
class method allows the screen saver view to select how the desktop
visibly transitions to the screen saver view. If this method
returns YES, the screen will gradually darken before the animation
begins. If it returns NO, the transition will be immediate. The
latter behavior is more appropriate if the screen saver animates a
screen shot of the desktop, as is the case for optical lens
effects. The default is YES.

I'm trying to create a screensaver that doesn't blank the screen;
essentially I need the desktop to remain visible while the
screensaver is running. It seems like the fade-to-black effect is
the default behavior whenever the OS activates a screensaver
bundle. Is there any way to override this?
