Some times 3d is only for fun. Here I did this video, inspired on a facebook video I saw.
Done in TP, and rendered in Arnold. The basics are the same as this ones: http://www.andvfx.com/2525/implicit-shape-uvw/ Only difference is that now we apply the material to spheres and not to implicit shape.
I used materials, you should be able to use vertex color for simplier TP setup. Only remember to enable on Arnold compatibility with 3dsmax shaders.
You can download the scenes here: Max (2016 and 2018, and TP).
