In this paper we present new versatile "2D macroscopic Wigner islands" useful to investigate the various behaviors observed in mesoscopic confined systems. Our "Wigner islands" consist of electrostatically interacting charged balls with millimeter size. We have experimentally determined the ground configurations for systems of N confined particles (N=1-30) and checked the influence of the confinement and interacting potentials. The results obtained are compared with the published numerical results.
