How to achieve Assasins Creed fragmented shader effect?

I've been searching since quite a while, means to achieve the effect, on mobile without insanely impacting the performance.

A suitable reference is the Fragmentum Shader on the store, but sadly it's not unity 5 compatible.

The other possible approach:

http://answers.unity3d.com/questions/338819/explode-a-mesh-into-polygons-efffect.html The problem I'm facing with this method is to move the fragmets from an arbitrary/random(but close) position to its respective position relative to original gameobject(which was initially fragmented) in some (performance friendly) way.Therefore a shader method could be more feasible(?).

Any help would be appreciated.Thanks
