Solution of the wave equation on a sphere. Reflecting obstacles have been placed around the vertices of a cube. The initial state is a set of circular waves of alternating sign, concentrated at the centers of the faces of the cube and on the centers of its edges. The video shows an equirectangular projection.

Solution of the wave equation on a sphere. Reflecting obstacles have been placed around the vertices of a cube. The initial state is composed circular waves concentrated at the centers of the faces of the cube, and on the midpoints of its edges. The colors and radial coordinate represent the wave height and averaged wave energy.
