A Tiny Clack

I shuffled forward on my big yellow shoes, discovering this wide wooden tabletop! Right in the middle sat a smooth, curious plastic brick with colorful rubber bumps. When I nudged it with both white-gloved hands, it wobbled, and my thumb accidentally pressed down on a soft red button. A tiny red light blinked on its front edge, and the giant dark screen across the room suddenly hummed with a quiet blue glow! I hopped back half a step in surprise, watching the faint reflection of my ears dance across the screen.
