Don’t you just sigh inwardly when you see a long flight of stairs right in front of you? Who looks forward to climbing them? I know I don’t. Not even if you promise me buns of steel after the arduous ascent. So it really helps if I see a staircase artfully treated in the most delightful of visuals. They certainly distract my unpleasant journey upwards as I pant my best to think how they go about making sure the entire piece works brilliantly when viewed upfront from afar.
