  The Crown of Thorns (puzzle work) is a woodworking technique of tramp art using interlocking wooden pieces that are notched to intersect at right angles forming joints and self-supporting objects, objects that have a "prickly" and transparent quality. Common examples include wreath-shaped picture frames that look similar to Jesus' "crown of thorns".
  
  Larger-scale crowns may use the principles of tensegrity structures, where the wooden sticks provide rigidity and separate cables in tension carry the forces that hold them together.
