General relativity may be formulated in terms of tetrad fields and of the torsion tensor, i.e. in an alternative geometrical formulation as shown in the review by J.W. Maluf (pp. 339–357). This teleparallel equivalent of general relativity has been expressed on the front page in an artistic vision by G. Schulz (Fussgoenheim, Germany).
