In this project, we have invented a new material especially for this art piece - a special synthetic material made by bamboo laminate and aluminium strips. We used a special production technique to avoid delamination of bamboo on aluminium. The strips combined the strength of bamboo’s elasticity and aluminum’s strength, a perfect material to solve the 10+m long-span issue. The flexibility of the material can also fully express the tree branches’ organic curvy form. Lighting are designed to allow lights to shine through the strips and create beautiful shadow underneath the installation art.
