In this paper we present some possibilities how different areas of visual mathematics (symmetry in art and science, isometric symmetry groups, similarity symmetry, modularity, antisymmetry, tessellations, theory of proportions, theory of visual perception, perspective, anamorphoses, visual illusions, ethnomathematics, mirror curves, op-tiles, fractal structures) can be used as a tool of visual communication. The paper also contains (in parts) a description of the course ``Visual Mathematics and Design'' organized at the Faculty of Information Technologies (Belgrade).
