Shiroshi by Haruki from uk
designer's own words:
Shiroshi is an exploration into the ephemeral beauty of light by looking at the qualities of movement. Interested in the quality of light, as much as the form, it mimics the ebb and flow of natural light by refracting light through water and lenses.
One of the main aims of this project was to look at how LED lights could be utilised in order to create a light of interest, referencing and reimagining the beauty of natural light.
Inside the light there are LED's connected to a computer chip which makes the light flicker and flow like natural light. After this the light travels through a two compartment water chamber, creating movement within the water, producing an effect where light now has movement, contrasting the overly quantitative, static modern artificial light, which lacks the tempo, wavelength, nuance and tone of beautiful natural light.
Inspired by the way traditional Japanese culture has historically handled light, with a reverence to shadows and the changing quality of light. Shiroshi aims to recreate the phenomenological approach of Japanese design, to create an awareness and appreciation of the qualities of subtle changing light, by exhibiting light that differs from functional task lighting.
Shiroshi is an exploration into the ephemeral beauty of light by recreating the qualities of natural light to LEDs.
Not designed as functional light, this effect could be utilised in places such as bars, restaurant or public spaces.
With a wire gutter at the back the design can placed on surfaces or hung at two different angles. 
Using moving water within the light, LEDs shine through the water to create light with vibrancy and movement.
The LEDs are also connected to an Arduino which is programmed to make the light dim and flow like natural light.
