For the surface shape, we have a function that gives the 3D position by basically getting the height in function of position on 2D plane. This height is computed with a sinusoid and with a delay that's the distance to center + the angle to this center (obtained with atan2 function).
A black mesh is drawn by drawing a lot of tiny triangles on the surface.
Some particles with random parameters/positions are drawn on the surface, moving outwards (simply moving in lines in the 2D parameters input of the surface). The replacement technique is used, and its parameters make them move at different speed compared to the mesh wave.
