Black to black dig into the possibilities of vertical layers of time, to express the struggling feeling. 
 
By layer and layer adding up to the film, we can feel the existence of time. Most of the time, we think that struggle is to break something. However, the struggle is like many things surrounded you and you can’t even breathe and move, and you still try not to let it beat you down. Sometimes we cannot even recognize ourselves when you being surrounded too much stuff like there are too many layers, the shape of us is all about the stuff, you look like a mess. The struggle is more like the stuff getting you crazy compared to emotion from the human mind. I let the fabric move more freely and obviously, it makes the object more live.
