An exploration of modular multiplication. The image is a voronoi diagram generated using points on a two-dimensional integer lattice. The set of points used to generate the diagram is precisely those points (x, y) for which x*y ≡ 121 modulo 1331. One may think of this in some sense, as a visualization of the Cayley table for the multiplicative group of integers modulo 1331.
