Schiena

The beams of light cast on the wall behind it, which constantly change into different combinations. 

The bookcase shows balance, movement and dynamism, which constantly interact with each other 
and are emphasized through the circular attachment plates, which remain lightly separated from the wall.
These plates are the physical connection between concept and reality. 
They show harmony without adding weight.
The bookcase can be made of different materials and colors, while the lights behind it are low energy LEDs.
