Blender Underground

If you've seen this past summer's 'Transformers' movie, then you're probably familiar with the scene towards the end of the film where Bumblebee reaches for the All Spark and it transforms/converts to a much smaller cube.

During the transformation it appears as if the All Spark is composed of several thousand cubes; well my question is: how could one animate a cube in Blender to do the same? Would you use Blender's array modifier or a series of modifiers?

Thanks!

Probably dupliverts. A pretty clear little explanation is here:

Dupliverts, array or particles can all do this I think, dunno which one is the best, though.
