Ruga Lumina

Width 15', Height 8'

Coroplast, video projection


Ruga Lumina had been installed at two sites: Detroit Center for Design Technology, Detroit, Michigan and

3Labs, Culver City, California


In Ruga Lumina, the latest iteration of  Ruga Interior Skin, interactive digital projection techniques are used to actively engage body-space relationship. As the viewers move in the space, their movements are captured by the Kinect Sensors and the information is translated into color changing information in the digital projections to be projected onto the translucent interior skin that is fabricated from 4 mm Coroplast sheets. A scaffolding that was made of cardboard and wooden rods was used to frame the somewhat flexible topology of the interior skin to facilitate the positioning and connecting of over seventy individual panels. Since the folding mechanism in each of the Coroplast panel is a flexible hinge joint, the edges of the interior skin are reinforced with fixed braces to give rigidity to this otherwise flexible topology.  Both flexible and rigid,  the interactive interior skin draws the connection between the body and the interior space, placing the dichotomy of permanent vs. ephemeral, solid vs. light, and materiality vs. digital fabrication at the center of the concept.
