Sinusoid I / II/ III/ IV / Time

Polycarbonate Origami Sculpture, 2013-2016
Sinusoid
investigates the resonance produced by repetitive oscillations of light. In this work, light behaves almost like a painterly gesture—moving across the surface and shifting in color to create a dynamic visual experience. The sculpture transforms illumination into a spatial phenomenon, where light appears to oscillate, diffuse, and interact with the surrounding environment.

The form is constructed from ready-made polycarbonate sheets, whose translucent and reflective properties generate rhythmic patterns of light and shadow. Inspired by Japanese origami techniques, the material is folded through scored lines that guide its transformation into a precise geometric structure.
Through this process, the sculpture becomes a device for modulating light. The folded surfaces refract and multiply illumination, producing subtle optical illusions that change depending on the viewer’s position. Light thus operates both as medium and subject, creating a shifting visual field that bridges sculpture, drawing, and painting.

Time
is Lighting and Sound Art Installation work created by Eiji Sumi and Treborikki Pomegranates in 2015 for Bangkok Illumination at Emquartier Park as Public Art Installation.

We all lives in time, Time is a measure in which events can be ordered from the past through the present into the future. Time is part of the fundamental structure of the universe, events, in which events occur in sequence. Time is fundamental intellectual structure (together with space and number) within which humans sequence and compare events.
And we all think we share same moment and time.  But Time also considered as spacetime consisting of “four dimension" compare to which regards space as consisting of “three dimensions”  With motion and space, we are not necessary share same time, when we move faster in motion, time move slower than the one who are not moving. Since, slow speed level where we move on earth, motion’s impact in time is so tiny.  After Albert Einstein’s theory “ Special Relativity” there was many experiment and it was proven fact that motion impact time.  So in fact we all live in same time but yet we are not necessary sharing exact same time. Sumi’s light installation work “ Time” creates clock format with the light with second, minute, and hour, and also indicate space time with motion although our sensory may not perceive that. Sumi’s work “ Time “ ask questions to audience time we live, time we move around the world, time we take an action with different ideology, philosophy, religion, ecology, politics and economy from all over the world.  With movement in motion, Are we able to live in different time, and create different world?
