Framed up

I saw this simple idea in the June 2008 UK Homes & Gardens. I liked how they positioned the frames so that they form a clean and contained area. Kind of a "picture made of pictures", as opposed to having it more free form. I'm thinking it could be a fun alternative for a wall that you want to have some sort of large impact . It think it's especially effective that they kept all the frames the same finish and with  the same color toned imagery.
