The screen flickers on the TV, blue and bright. Numbers flash in white, quick and busy. A sound beeps sharply, like someone tapping a finger. The screen goes dark, then lights up again. Something moves inside it, tiny lines drawing shapes. It’s wiggly and fuzzy at first, but gets clearer. A car shape appears, shiny black with red and blue lights spinning around the wheels. The car zooms across the screen, leaving a trail of bright green. It stops suddenly, then starts again, faster this time. The screen goes blank for a moment before showing more shapes dancing across it.
