100,000 LED lights to light up the Sumida River

Tokyo has always been a mistery to me, one of these cities that will you blow away for sure. What follows would certainly water my eyes. At the occasion of the Tokyo Hotaru festival that just happened, one of a kind of installation was made where LED lights were the main ingredient. LED lights are awesome, aren’t they?

100,000 LED lights, that is what it took to give to the onlookers an astonishing spectacle. The aim here was to suggest hotaru (fireflies) with those lights that floated down the Sumida River through central Tokyo.

Beyond the purdy effect, let’s note that the LEDs were¬† designed to light up upon contact with water and were 100% powered by solar energy. Let’s also mention the reference to a long gone practice were people used to to gather, it seems,¬† around clean, running water, searching for these luminous creatures.

Video painting at Cordy house, London

Video installation by the creative Brooklyn duo Sweatshoppe. The principle is simple: a LED roller paints video onto a wall. The effect is guaranteed.

Thanks to the programming language called Max/MSP, Blake Shaw wrote a software that makes possible the projection of video visible when it comes in contact with the LED lights on the roller.

The video below is Sweatshoppe at it on top of Cordy House, Shoredith, London towards the end of last year.

The billboard art project

Some will tell you how ugly all these road signs, billboards and others are and how much they give our cities an ugly look. This is when The Billboard Art Project comes in with a awesome idea which surely will enhance the city landscape.

They acquire digital LED billboards normally used for advertising and repurpose them as roadside galleries. .Projects are currently held in various US cities only.

What makes this project even better is that it is open to anyone who is interested in contributing. The type of artwork consists of images specifically created for the medium or art turned into the required format. And you should never get bored since artwork rotates every 6-10 seconds.

Immaterials: light painting WiFi networks

Light Painting WiFi is the creation of Timo Arnall, Jorn Knutsen, Einar Sneve Martinussen. Their work explores the invisible terrain of WiFi networks in Oslo urban spaces.

They put together a four-meter tall measuring rod with 80 points of light reveals cross-sections through WiFi networks using a photographic technique called light-painting. By the simple action of walking down streets, they are able to pick up the thousands of WiFi signals and with the help of a long exposure camera, transform them into wall, barriers of lights.

Beyond the art aspect of this work, this technique has also a research purpose as the data collected is used to evaluate the quality of the Oslo wireless networks.
