Chic groups of Art

I have a client who, luckily, has an extremely large living room. The only problem is...
that above the sofa, we are having problems finding are that we love that fills the space. It's a pretty big wall. So, I'm pushing for a grouping of framed smaller art pieces that go together.
It makes such an impact and the frames add an architectural detail which is just a bonus to the artwork. 
I also like them placed in order, not arranged in random order. There is something grand about an organized arrangement that makes the room more dramatic and bold.
