This is not a girl trapped in Tron or in a holodeck, and those lines aren't lasers. What you're seeing here the work of Jeongmoon Choi, a Berlin-based artist who uses colored thread and UV lights to illuminate her creations as three-dimensional installations.
According to the Galerie Laurent Mueller, where "Dialogue Lineaire" is displaying until January 26th:
Jeongmoon Choi works with thread and traces this three-dimensional line directly into volume to create illusions of perspective. The thread is coloured and used to outline or redefine the architecture of the spaces the artist invests. Drawing directly into space with her hand, the artist addresses questions about our environment, as well as about aspects of lodging and the role of nature in our urban spaces.
The drawings become project or even projection of an imaginary construction that takes form in its environment starting from a line, a thread, which represents the chronological decisions of a progression in space. The transition from a plane to a volume is just as important as the comparison between interior space for living and exterior space for living.
For those who can't make it to Paris to see "Dialogue Lineaire" in person, you can flip through it virtually in the gallery below. You'll wish you were in Paris by the time you finish.
