This project explores the potential for lightweight kinetic architecture.  Using both physical prototypes and parametric models, a system of mechanized units is developed to produce a transformable structure.  The process began by testing connections between paper strips to create a laminated, shell-like structure.  By changing connection points along a continuous range and producing fixed prototypes of each result, we visualize stages along a potential range of motion. Two sliding connections comprised of a servo fixed to a geared track, one parallel near the strip’s edge and one transverse at the center, produce all of the variation we use for the design.  The movement is programmed through Arduino to respond to sound using audio sensors.

The architectural proposal uses this system to create sonically responsive public space.  A performance space for subway buskers creates enclosure for the Civic Center BART station in SF.  As a sensor network locates musicians within the space, the structure responds accordingly, forming various listening zones based on acoustic reflection.
