Mini cam/duplicate of main camera view

Hi,

I am working on this project. We need to "fake" the taking of a photo, as to do a real jpeg encoding would take up too much room. (This is for a museum kiosk)

The game is normally shown in 3rd person, but when the user gets into this interactive zone, the view switches to 1st person. We then have camera panning controls, and a "Take Photo" button.

So what I want is when the user clicks the "Take Photo" button, all the panning controls freeze, and a duplicate of the main 1st person camera to show a reduced in size view of the main 1st person camera in a little window on the screen, over our gui.(Must show just what the main camera is showing...just smaller, and in a window)

Then in the same little window, we want a little space for a png sequence/animation to play, and when that animation is over, the little window disappears, and we roll back into our 3rd person view.
