help!

in our "music room" (aka, where ac plays guitar) we're just starting to put things together. wednesday and thursday i painted the whole thing a neutral color (benjamin moore, stingray) to match the bedroom (benjamin moore, senora gray) and ac got started on putting the books back (before anyone flips out- that's not the way they'll look, we just wanted to get them off of the floor last night). we have plans to hang all of our guitars on the wall and frame a series of chris ware prints, but now i'm faced with that dinky little window in the corner. i hate it as is (it opens to a lovely rundown airshaft between the floors) so i need to do something with it. but what? a tiny roman shade? i'm so confused on this one i thought i'd open it up to you guys. your advice has been so spot on this week i thought surely someone out there knows better than i do what to do with our weird half window. (also, this is the room where the rocking chair will be. i think i'm going with the fig or espresso beads. ac likes the fig). thanks guys! your two cents is much appreciated.
