Tried to recreate the effect made from Rayfire plugin used for 3ds max.

Ah, so the sixteen pairs of blocks are pre-fractured. Did you use the cell fracture add-on? I watched your video and then went looking for Blender destruction videos and found one by Blender Cookie ("Using the Cell Fracture Add-on in Blender - Part 01").
I really like the effect. If the pieces were small enough, one could make an animation of a mole-infested lawn LOL
How did you do this I have been looking for a way to set up a animation like this.
Good animation!
