Anyone know what program the Apple store demos likely use to make their interactive desktop

I have a project that I am attempting to do and we want something similar to what the Apple store does. We thought it was a Quartz Composer interactive desktop but I've been putting together an xcode cocoa solution to do it too.

Here is an image of what I'm wondering about it is just a Title and 3 images that link out to url locations. If anyone can point me in the direction they believe can make something like this I would appreciate it.

I have used Quartz Desktop to display a .qtz but it isn't interactive. If anyone knows of another quartz desktop displaying .app that does u开发者_Python百科se the interactive parts such as mouse and keyboard, it would be appreciated.

It's a custom proprietary program called, if I remember correctly, Concierge. But it's not doing anything tricky. You can make any NSWindow appear on the desktop by setting its window level to kCGDesktopWindowLevel.
