Nano tech effect

[Thanachai]

This is the closest I can get to replicating the nano tech effect in Avengers. Anyone know how i can improve it? I am using a brick fracture for the individual blocks but, this causes a non smooth surface while rendering and it's obvious. It also doesnt have much detail like the one in he movie. I tried thinking of a way to create a bunch of tiny little 'nano particles' instead of using a brick fracture.
