We prove a new integrability principle for gradient variational problems in ℝ2, showing that solutions are explicitly parameterized by κ-harmonic functions, that is, functions which are harmonic for the laplacian with varying conductivity κ, where κ is the square root of the Hessian determinant of the surface tension.
