The Dilemma ( not the movie )

I move things around alot in our house, i like to switch things up... but now i don't know what to do with this wall..
I was thinking old windows... but this room already has lots of windows.. would that look weird?
or
i could win the lotto and buy a huge $1,000,00,000,000,000 way cool picture
I have no idea... Im loosing all of my creative juices...
I want something rustic antique......
