X_M of M independent NxN Gaussian random matrices in the large-N limit is rotationally symmetric in the complex plane and is given by a simple expression rho(z,\\bar{z}) = 1/(M\\pi\\sigma^2} |z|^{-2+2/M} for |z|<\\sigma, and is zero for |z|> \\sigma. The parameter \\sigma corresponds to the radius of the circular support and is related to the amplitude of the Gaussian fluctuations. This form of the eigenvalue density is highly universal. It is identical for products of Gaussian Hermitian, non-Hermitian, real or complex random matrices.
