Forget "birds", I say put an angle on it! (FYI: funky lines and playful angles are a sure-fire way to my heart.) This set of nesting shelves can be stacked or mounted on the wall - it would be fun to get a few sets for a large wall or paint them in subtle gradations. Endless possibilities and arrangements!
