Here's a way to do it. The meat of it is to take a line and divide a polygon into two. Then you can utilize a mesh distort to apply a polygon to a sprite. The more complex part was to eliminate bad edge cases.
When you right click on the sprite it divides it in two then divides one of the halves in two as well. There are probably other strategies to break things up.

Your example is spectacular.
