What do you think would be the best way to animate the greebles floating around this spaceship, shape keys or lots of little bones?

Thanks for any thoughts.

Explode modifier and weight paints.

What would that achieve scrag_10?
I don’t want to explode them, so much as move them around, and in and out.

Or the particle system set to use a group with Random turned on . Add all your greebles to the same group and let the system deploy them randomly.
