Approximating the charge density in crystalline gallium arsenide by a spatial superposition of self-consistent charge densities of gallium and arsenic atoms, we have calculated several contours of constant charge density and examined the three-dimensional character of these contours. A novel feature of the present work is that computer graphics techniques have been used to present the results in the form of three short color movies.
