Just messing with the Cell Fracture add-on

So I tested the Cell Fracture add-on that comes with Blender, and these are the results. I ripped the sound off Half-Life 2.
I found a way to keep the physics off until I want them to go. (by myself)
I also found a way to hide the cracks, but I found it later so it’s not shown here.

Feedback (bad or good) is appreciated
