   Actually, I take back the first part, I misremembered the premise of Flatland.   
   A spiral coil in Flatland perpendicular to its plane would look like a small   
   oval, and the oval would move around in circles as the coil moved up or down   
   through Flatland.   
      
   Anthony is not entirely off-base about it having circular properties; a coil   
   viewed from the front in two dimensions *would* appear as a circle if you   
   removed all perspective. Otherwise it would appear as, obviously, a spiral   
   becausue it regresses into    
   the distance. The tightness of the spiral would then depend on how stretched   
   the coil is. An even coil would appear as a very tight spiral.
