Here is a simulation I did yesterday. The goal of it was to have a fracture shard fracture again when it hits the floor. Sounds simple but it is not anyway it involves a lot of blender game logic but here it is . The fancy double fracture object is the large on on the right side that splits into two peaces (double fracture).
I am looking to post more drawings soon but right now 3d stuff is all I have at hand.
