Usage examples of swingbridge.

It seemed to take Spencer an age to turn, as if his body were a swingbridge powered by a hamster on a wheel, his arm the shadow on a sundial, rising imperceptibly each minute, the gun impossibly weighing the shadow down, until a lazy afternoon passes by and the gun is in place, the trigger finger, arthritic and torpid, crawls back towards the palm, the bullet leaves the barrel, wipes its eyes in the bright light, yawns, stretches, and wanders off lamely in the direction of Kohl's skull.
