/*
 * The destination blind (includes/pieces/blind.php): a steel blind box on the station's stone wall,
 * an enamel plate, a window onto a drum of black linen printed in white (a CSS 3D prism, one face
 * for each year of birth, the lines above and below curving away into the dark), and the winding
 * crank on its side. The line at rest faces you flat, so it reads as print.
