PERPETUAL CURVES by sang jun yoo from usa

beauty throughout our environment is likened to curves. curves by nature represent an incredibly articulated composition in balance, also a contrast between hardness and sophistication, ‘perpetual curves’ shares this idea. the perpetual movement of natural curves symbolizes an infinite expedition by the innovated force.

audiences are welcomed to join an wind-activated, sensory installation. ‘perpetual curves’ realizes three-dimensional curves with an Infinity car. It also elicits audiences’ emotional response to locate their own sensory experiences into various translations. this experimental installation invites us to see through the curved visions: how an Infinity car interacts with unlimited nature and creates infinite possibilities driven by a simple curved line.

//description of the project :
“perpetual curves” is an wind-activated installation, mainly composed with a sheer fabric curtain, kinect sensor, and a car, which focuses on interpreting infiniti car’s body lines and visualizes what makes these graceful and powerful curved lines. from this, we want to make the audiences participate and experience what they look beyond of the curved vision: infinite possibilities driven by a simple curved line.

a constantly moving curtain with the lights mimics the characteristic of curved vision, which represents an infinite movement. the curves on the moving curtain helps the viewers to experience an invisible force that drives the atmosphere in the space. experiencing the installation is meant to elicit an emotional response too. the viewers become able to be immersed in the curved vision which drives a self motivation to discover their own perspective in between perpetual movement of curved lines. the viewers can directly approach to the inside or the outside of curtain wall, also adjusting the curves and the light on the curtain, to experience a spatial interactivity in the installation space. by touching the lights on a moving curtain wall over the car, the viewers become able to change the curves and the color spectrum, also their own visual perceptions to the curved vision. the constantly changing color spectrums on the curtain illuminates the car’s body as well. the curved vision in the installation naturally harmonizes with the curves on the car’s body. the translucent swathes mimic the movement of fabric in front of an open window, also the depth of natural encounters in our daily lives.

//installation a :
installation a (focuses on the relationship between car’s curvy outlines and wind)
a light sheer fabric is spreading over the car’s body , and flowing air in between the fabric and the car’s outline maintains a flexible open-space for recreational curves. the fabric is responsive to the delicate changes in the wind and users, and a hidden motion based camera right above the car captures invisible and subtle changes. it also converts these into a visible color gradation to aim for emphasizing the car’s curvy outlines.
the viewers are able to touch the moving curtain over the car to change the curves and the color of the lights. and the curved lights illuminate the car's whole body.

//installation b & c (shows the concept well, “beauty by nature” on purpose of exhibition) :
a sheer fabric is falling down in front of the car, and only top parts of the fabric is fixed, so it is allowed to blew by wind or controlled by audiences. this is to visualize invisible wind, creates and changes the colors and curved shapes from its flow, so audiences are allowed to experience more directly and feel the relationship between natural beauty and car.

//technical details
- the installation includes following initial equipments: projector, sheer fabric curtain, oscillating fan, kinect sensor, computer. sheer curtain is hanged on the ceiling by transparent threads (set a), or any hanging materials such as a wire hanger or a mobile stand (set b & c).
projector and sensor is mounted together with facing the curtain wall. the sensor collects a distance data to the surface of the curtain which is constantly moving by the oscillating fan. the projector generates a smooth color spectrum on the moving part of the curtain based on the collected data: brighter(close) ~ darker(far) spectrum. the color palette can be modified in real time. the color spectrum is changing by the viewer's direct touch, also can be set to be changed automatically on a time basis. as the curtain is constantly moving by a wind current from the oscillating fan, the light is being projected on the curtain continuously. the viewers can control the fabric curtain front and back, to experience the spatial interactivity with the moving curves of the fabric and the light in the installation space.
