In the movie Super 8, there's a sort of technology that I don't think I've seen before. Part of the plot of the film revolves around an alien. Some of this alien's technology I don't think I've seen before. I'll spoiler the specifics of the question, as the mystery of the alien is central to the story.
The alien's ship, when it broke, dissolved into many small white blocks. As near as I can tell, these blocks, when properly controlled/guided combine and change into the structure of the ship. So the white blocks turn into a metallic hull, a central power-core, and thrusters. They're like a macroscopic version of nanites that can be reconfigured into all manner of other forms of matter.
Is there a name for this type of technology?
