What I'd like to do is display a Desktop preview of another Space the exact same way the current implementation of Spaces shows previews of all other Desktops. I've provided a graphic at the bottom for visual reference. You can see on Desktop 1 I'm on StackOverflow and on Desktop 2 I'm watching a video on youtube. In Spaces, even if I'm on Desktop 1, I can still see the small preview of Desktop 2 with the video playing. In short what I'd like to do is implement the same functionality in my application where I grab that same feed Spaces uses (where if a video were playing, I'd see it play) and put it in an NSView of my main application window. Is this at all possible?
