When the living room feels over-arranged, this kind of abstract helps. It brings noise and movement to a room where everything else has been carefully matched. Colour does the work here: deep blue and purple hold the middle, while orange, hot pink and turquoise break in from the edges. Hang it above a sofa, on a chimney breast, or on a plain wall at the end of a room where you want the eye to travel. Keep the surroundings simple. Solid colours, plain linen, dark wood, one or two ceramics. Skip busy patterned wallpaper, floral curtains or a crowded shelf directly beneath it, or the whole wall turns to visual chatter. On premium fine-art paper, the splattered detail and edges of colour stay crisp.
