A strange little side quest
The mechanics around Decor: My Library have roots that stretch far beyond modern browsers. By the 1890s, department stores and mail-order catalogs were selling mass-produced ready-to-wear clothes in standardized styles and price ranges. A second detail makes the picture even better: In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. That gives Decor: My Library a little more company than it first appears to have.
