  We study numerically the geometric properties of reduced supersymmetric
non-compact SU(N) Yang-Mills integrals in D=4 dimensions, for N = 2,3, ..., 8.
We show that in the range of large eigenvalues of the matrices A^mu, the
original D-dimensional rotational symmetry is spontaneously broken and the
dominating field configurations become one-dimensional, as anticipated by
studies of the underlying surface theory. We also discuss possible implications
of our results for the IKKT model.
