/* The answering machine, about 1985.

   Beige plastic on a dark desk. The machine is built from five things and all
   of them are cheap: a rounded box with a warm gradient, a speaker grille made
   of a repeated radial dot, a sunken tape window with two reels, a red counter
   digit, and four chunky buttons with a real bevel on them.

   The bevel is the detail that sells it. A button from 1985 had a light top
   edge and a dark bottom one and it moved down when pressed, and that is two
   box-shadows and a transform. Nothing here is an image. */
