boustrophedon

( n.)

   [from  a  Greek word for turning like an ox while plowing] An ancient
   method  of  writing  using  alternate left-to-right and right-to-left
   lines. This term is actually philologists' techspeak and typesetters'
   jargon.  Erudite hackers use it for an optimization performed by some
   computer typesetting software and moving-head printers. The adverbial
   form   `boustrophedonically'  is  also  found  (hackers  purely  love
   constructions like this).
