In the process of negotiating with shadowline, I found some possibilities, and looking forward to the next materials development.

For architects and interior designers, shadowline is an architecture decoration material, 
which designers use every performance way and change to convey their creative design.

When making up a light environment and light-model design, it's a medium and carrier,
adding more colors and words to the art performance.
Furthermore, open up the spectrum of environment art.
Light is environment, the whole move in the space, to be put as the first decisive condition.

Design without the light, the space would drown in a dark and become valueless.
