   Seasonal carousel — All In House

   The covers of the latest posts stand on a cylinder and turn past
   the visitor, the way a carousel turns. One number, --deg, is written
   on the ring by season.js; every card sits at its own angle on the
   drum and the drum's rotation carries it round. Sits on the same ink
   as the orbit rings, in the same vocabulary.
