Interactive Art Installation
Lumibolic is an interactive and occupiable environment shaped from hyperbolic paraboloid geometries. Its luminous surfaces are composed of strands of glowing EL wire that modulate their form and intensity in response to sound and motion inputs. Designed to generate dynamic visual vibrations inspired by the work of Op-Artists Bridget Riley and Victor Vasarely, the piece visualizes relationships between site and visitor on a large scale.
UNIQUE PROPERTIES / PROJECT DESCRIPTION:
Lumibolic is an interactive art installation which responds to sound and motion. Presented and co-produced by LERATA and Arts Brookfield, Lumibolic was a winner of the LA Skyline 2016 competition and was exhibited at Bank of America Plaza in downtown Los Angeles from February 11th thru March 18th, 2016. Created out of 1,200 meters of EL Wire, the installation visualizes sound and motion within its surrounding environment through dynamic lighting patterns. A total of 48 strands respond individually to volume levels while motion sensors activate and deactivate geometries within the Lumibolic based on visitors' motion.
OPERATION / FLOW / INTERACTION:
The interactive scenarios are programmed to operate in two different modes: motion-based and sound-based. Each strand is activated based on the interaction with viewers. For motion-based mode, all visual effects are activated by motion sensors. During normal inactive hours, Lumibolic is set to a breathing mode which is a pre-programmed mode with slow visual motions created by partial strands without revealing the overall shape. When each motion sensor is triggered by a viewer, Lumibolic performs dynamic pre-programmed movements in a sequence activating different groups of strands with various visual effects.
For the sound-based mode, the El wire responds to either live sound or audio based on the volume level of the input. The input activates the El wires accordingly in a sequence creating dynamic visual movements. Viewers are able to add their own visual patterns utilizing the motion sensor pad to create their own effects.
PROJECT DURATION AND LOCATION:
The project was exhibited in Bank of America Plaza, downtown Los Angeles from Feb 11th~ March 19th, 2016.

PRODUCTION / REALIZATION TECHNOLOGY:
Lumibolic is a space frame derived from combinations of hyperbolic paraboloids that visualize sound and motion. Consisting of twelve half parabolic surfaces, each housing 24 strands of electroluminescent wire, the piece creates movement and a variety of visual effects from different vantage points. Each parabolic surface unit is comprised of a series of linear elements which are individually activated by electrical current, in response to sound and motion inputs. The voids between the EL Wire linear elements facilitate varying views of overlapping geometries from different vantage points. The space frame structure is made of PVC pipe and 3d printed joints finished with polyurethane paint that adds high gloss and protects the surfaces.

As an interactive installation, created from hyperbolic paraboloid geometries composed of two-thirds of a mile of glowing EL wire, Lumibolic creates an interactive space-time experience utilizing visual and optical illusions inspired by Op-Artists such as Bridget Riley and Victor Vasarely. By linking motion and sound through modulating lighting effects that produce dynamic visual vibration, the installation creates relationships between site and visitor. The installation utilizes low electricity EL wire as its light source with a suite of sensors. These EL wires are strung within rationalized and rotated half-hyperbolic paraboloid surface frames that blur boundaries between exterior and interior. The layered half-hyperbolic paraboloid forms produce concentrations of light lines which express themselves as arching forms that modulate in front of visitors’ eyes as they walk around Lumibolic. From specific angles these lines may appear to cross through others, or appear more vibrantly as a result of optical illusions such as White’s, Haze, and Criss-Cross. Motion and sound sensors, positioned at strategic spatial positions, are choreographed to trigger crescendoing levels of dynamic lighting effects. These light patterns utilize several optical illusions to further experiences of dynamic visual vibration. When linked with musical performances, the light levels within the piece vibrate in patterns responding to fluctuating sound volumes.
The challenge of the installation is to find the most sensitive and efficient way to engage public with the sensors. As a public plaza, there is a constant flow of people passing by with random destinations which makes the activities hardly predictable. Creating a clear scenario for interactivity based on the understanding of the social behavior of the audience is important for the development of the project.
