Ball Wall

For the 2014 solar decathlon entry between Brown University and RISD, we were tasked to create a one of a kind physical experience using our partner company's photo luminescent paint. Our goal was to give viewers not only a chance to experience the house, but for them to leave their mark behind.  

The result was an interactive network of spheres acting that act as individual pixels, allowing the participants to leave a gestural mark within the space. 

​

Each module is composed of 61 spheres sandwiched between two sheets of laser cut acrylic, allowing each sphere to rotate 360 degrees in every direction. During the day, the sun charges only half of each sphere, so that as the sun goes down, the front half of each ball begins to glow. The user swipes his/ her hand across the surface, hiding the glow side, and exposing a dark space. This allows the participant to change these “pixels” from on to off, and vise versa throughout the course of the night, with just a swipe of the hand. Ball Wall is an ever evolving drawing. As the sun comes up the next morning, the process begins anew.
