Semantically, a labyrinth is a meandering path that simply winds its way from start to finish like the grooves on vinyl. Mazes have forks, dead-ends and cycles but are conceptually the dual or the space between the grooves, where the complexity lies. Artistically, these structures are immortalized in the work of Salvador Dali , M.C. Escher , Keith Haring and recently Mo Morales . The organic labyrinths you see below are created with curves evolving under the forces of nature, guided by an artistic hand.
