If pinball is going to come back, to regain rock-opera level cultural primacy rather than more pizza-parlor corner dust, it probably starts with scenes such as this. In the foreground there is a father, petroleum engineer Mark Henderson. “My son’s Joshua,” he says. “He is 11 years old. He’s a pinball wizard out of Plainfield, Ill.” In the background there is Josh, a tall, bespectacled boy, leaning into a pinball game with a NASCAR theme. His look is intent, his chest touching the table’s end, his eyes over the top of the flippers.
