   CampusKart · "Campus notice board"
   The department notice board, made searchable. A walnut frame holds
   a cork board; listings are paper slips whose colour codes the
   category, held by brass pins, with tear-off tabs at the foot.
   Red (the pushpin) is spent on the one next action per screen.
   The AI writes its notes by hand, in ballpoint blue.
