The concept of this collage is about the flow out of the boundary.  I created the flow itself with the computer and ended with the sharp ages.  Then the flow keep continue out of the boundary itself and become other materials.   I felt that I didn't take as much risk in this collage as much as I wanted to.  But this is my first time using laser cut to do any of my project.   I thought I would ruin the laser cut work with salt and coffee.  But turn out salt and coffee alone would have been great.
