School's Out--but on 'Minecraft,' Graduation Day Goes On

The lectern stands before a vast, grassy amphitheater. Above, the sky is a pristine blue, the cloudless quintessence of a spring morning. Perhaps the most arresting feature in this panorama is the stage: a towering neoclassical structure with Doric columns that soar heavenward. Suspended from the columns are banners emblazoned with the letters QU, for Quaranteen University. The name is a wink from the worldbuilders--college and high school students, homebound for weeks now--about the surreal circumstances of their situation.
