For a project, I want to show some developments, and I thought a cool way to do this would be like found in the Cinema 4D 2008 Showreel. Basically, there is a bunch of black balls that are formed into a shape, the video is a guitar. Then, the balls “explode”, or all kind of go outwards, and comeback to form a new shape, such as a drumset. This makes alot more sense if you see the video:http://www.youtube.com/watch?v=KJSOsyImbF0 at 3:05

My question is what would be the best approach to do this? I am thinking of using a mesh with halo render(Or whatever it is to put spheres at verticies), and then shape keys. Is this a good plan?

Has anyone tried doing something like this keying every single ball?

hmmm well, i think a different approach would be instancing spheres and with keyed particles.
