Shape changing robotic chandelier for the Swarovski crystal company.
Esthetic design by Yves Bahar, electronic/mechanical design by Zach Radding

Some early construction photos.
 
You can see the six motorized cables that pull inward to deform the two spring steel rings.
Here it is with all 15,000 crystals hung.
Installed for fashion week in Milan
We built two sizes (the larger one is approx. 15' in diameter). This image also shows the chandelier's color changing ability.
We also installed the larger version in Miami during Art Basel.
This interface was installed on a wireless tablet PC and allowed the user to control the shape and color of the chandelier.
Me.
