1. Create Soft Body object.
2. Separate all faces from each other.
Therefor you can use the old trick, in Edit Mode: extrude "Individual Faces", invert selection, delete.
3. Set a Breaking Limit in the Soft Body Edges panel above 0.
How it works
The system basically detects what vertices are overlapping and internally adds stress sensitive constraints to keep them together.
people have been bugging me ever since the first Blender 2.5 alpha appeared to port the Demolition Script to the new API. Some even offered funding for that, so I thought why not make it my second community driven project.
I want to take the opportunity to recode it from scratch in C. I'm currently evaluating different ways of implementation to find a nice and minimally invasive solution, which hopefully not only improves the flexibily for artists but makes it more easy to use. It will probably not be as sophisticated as DMM, but it will be free and our own. After all we still don't have anything comparable in Blender.
For those who have never heard of the Demolition Script, I want to explain in short what it does. It's a system that performs tearing, fracturing, shattering and breaking like effects on meshes, based on the occurrence of stresses within the structure during a physics simulation like the softbody system.
Even though I'm going to try to release something to play with as early as possible, this project in general will be a long term project. I can remember I sat half a year at the basics of Demolition 1, although I partially reinvented the wheel by making my own softbody system for it.

My own demos put together in a showreel:
Interesting user made demos I have found:
I plan to work out a roadmap shortly, depending on the way of implementation I'm going to choose and the funding available. You can help to speed up development by making a donation.
All money will only be used for R&D of this project, BTW. Thank you.
