A Click in the Dark

Clumping off the sofa cushion, I headed straight for a mysterious white cylinder resting on the floor. It had a neat little rocker switch right on its power cord! I stomped right up, leaned all my weight onto my foot, and pressed down hard. Click! A warm amber glow burst right out of the lampshade overhead, washing the whole corner in bright golden light. What a tempo change! I tapped the smooth switch once more with my heel just to hear that solid, snappy rhythm again.
