My roommate is leaving me for a new apartment and I've been hired as her personal decorator. But we are both absolutely baffled as to what to put in this weird little corner she's got in the foyer outside living room. I suggested a waterfall but that isn't exactly cost effective now is it? She's not interested in making it functional so it doesn't need to have a purpose, just be decorative. No desks, definitely no bookshelves. Help please.
