Fake Window

I thought of this awesome idea that I'm going to do for one of my walls in my new home. I'm actually getting this huge poster (3 feet by 4 feet), and I'm going to cut it up into 9 pieces, and put each piece in it's own frame. Then I'm going to line the frames up, and put curtains on either side. The frames are really plain, so it's going to look like an intact window, and I think it'll be really impressive.
