[Ultra] is a spectacular large-sized light installation series.
The intention of this series is to change viewer's measurement perception of him/herself and the surroundings with the visual experience the installation provides.

[Ultra Line] is a floating physical light beam pointed to the sky.
Actions correspond to relative actions taken place in the environment, and consequently a visual experience of artificial lightning would be created. 
(The length of each line in this version is 20 metres.)
