Ah, I see... It appears to be made of a thin shiny piece of plastic overtop of the back. You might be able to peel it off. Or you might scratch the heck out of the back, and make a big mess of it...
It also appears that you should be able to scrape off the paint that says "3.2 Mega Pixels" (it's not embossed or anything), and then a shot of black paint (or electical tape) on the inside should fix it. I can try the electrical tape tonight, and see how obvious it is still (and post a picture).
