Glow Threads
Interactive UV light responsive t-shirts which are commercially available:
Glow Thread shirts are the first interactive glow in the dark t-shirts. You are able to to draw and create custom designs using our UV keychain light and UV Laser. Our UV keychain light is included with every purchase which allows you to draw on our shirts by touching the UV light to the shirt and write whatever you want. Using the UV laser you can draw on the shirt from up to 40ft away. Unlike other Glow Thread “imitators” where you are limited to a silk screened rectangle to draw on, our Glow Thread shirts are fully customizable and you are able to draw on every piece of the t-shirt. This means there is NO silk screened area and you are able to draw on the front, back, sides and even the sleeves.
You can find out more and order one from Glow Threads here

Abstract Christmas tree sparks protests in Brussels
An updated version of a post made earlier today, now with a video from BBC News
A minimal voxelesque Christmas tree with projection mapping and a staircase to view from it’s top hasn’t gone down well with some …
Thousands of people have signed a petition against an abstract light installation replacing the traditional Christmas tree in Brussels city centre.
More than 11,000 signatures have been gathered in the online petition and a Facebook page attacking the new feature has been launched.
Critics accuse officials of opting for the installation for fear of offending non-Christians, especially Muslims.
Maddy Savage reports.

Phantom Geometry
Experimental 3D printing using special UV light responsive resin, by Liz and Kyle von Hasseln:
Phantom Geometry from Liz and Kyle von Hasseln on Vimeo.
This is ‘Phantom Geometry’, a masters thesis in architecture by Kyle von Hasseln and Liz von Hasseln, developed in the Robot House at the Southern California Institute of Architecture (SCI_Arc). It was awarded the inaugural Gehry Prize at the SCI-Arc commencement ceremony on September 9.
This work is centered on the development of a system for generating material volume from streaming information. The system uses UV light from a modified DLP projector to continuously and selectively cure photo initiated resin within a shallow vat system we developed for the project. The cured part is simultaneously and continually pulled away from the vat, allowing un-cured resin to flood in beneath it to be subsequently cured. The result is the material reification of streaming data that emerges along the motion path of the Staubli robot maneuvering the vat/projector apparatus.
This system of fabrication relies upon native real-time feed-back and feed-forward mechanisms, and is therefore interruptible and corruptible at any time. The streaming data input may be transformed or modified at any time, and such interventions impact emerging downstream geometry.

Chiaroscuro (Étude Op. 3, No.3) by Sougwen
Installation where drawing and projection meet to create a different experience - video embedded below:
Chiaroscuro (Étude Op. 3, No.3) from sougwen on Vimeo.
Ink on paper | Projection & LEDs | 8ft x 5.5ft | 2012
Chiaroscuro is an installation piece that utilizes light as an artifice of visual perception. It explores the interplay of light and shadow on a dimensional drawing form. Strata of abstract, monochromatic line-work are suspended on a wall, giving off the illusion that lines themselves are extending beyond the flat plane. Coils of light are nested asymmetrically within the form, responding to the variations of sound in the environment and illuminating the surface with a pulsing ambiance. Projected light is mapped onto the exterior from a distance, revealing and obscuring the piece throughout the course of the installation.
Exhibited at “Of Art and Artifice” hosted by Ghostly International at The Art Directors Club Gallery in NYC.

Experimental 3D Mapping of Cities with a Webcam, Sunlight, and Time
Clever and inventive approach to large scale 3D modelling, using sunlight and shadow to calculate form (called ‘Heliocentric Stereo’) - from Austin Abrams:
In this work, we present a method to uncover shape from webcams “in the wild.” We present a variant of photometric stereo which uses the sun as a distant light source, so that lighting direction can be computed from known GPS and timestamps. We propose an iterative, non-linear optimization process that optimizes the error in reproducing all images from an extended time-lapse with an image formation model that accounts for ambient lighting, shadows, changing light color, dense surface normal maps, radiometric calibration, and exposure. Unlike many approaches to uncalibrated outdoor image analysis, this procedure is automatic, and we report quantitative results by comparing extracted surface normals to Google Earth 3D models. We evaluate this procedure on data from a varied set of scenes and emphasize the advantages of including imagery from many months.

Snail Trail by Philipp Artus
Great installation / stop-motion animation of “A snail invents the wheel and goes through a cultural evolution to finally get back to its origin.” created with a computer controlled laser on a phosphorescent surface, briefly absorbing the light.
Below are videos of both the animation and laser sculpture:

It has a low vector look about it, makes me think of Vib Ribbon and Sonic The Hedgehog.

Adagio for Jon and Helena
A contemporary example of liquid light projection, which is abstract and natural, yet produces alien forms. But together by Michael Scroggins:
“Adagio for Jon and Helena” (2009, 5:02, HD 1080p reduced to 720p for Vimeo) is a continuous take digital recording of a live solo liquid light projection performance dedicated to my liquid light teachers Jon Greene and Helena Lebrun. Jon Greene studied liquid light projection with Helena Lebrun who had studied with liquid light projection pioneer Elias Romero.

Photografting Shapes with Laser Light and Molecules
Similar to 3D printing, but using laser light to create forms at a molecular level - via Science Daily:
With laser beams, molecules can be fixed at exactly the right position in a three dimensional material. The new method developed at the Vienna University of Technology can be used to grow biological tissue or to create micro sensors.
There are many ways to create three dimensional objects on a micrometer scale. But how can the chemical properties of a material be tuned at micrometer precision? Scientists at the Vienna University of Technology developed a method to attach molecules at exactly the right place. When biological tissue is grown, this method can allow the positioning of chemical signals, telling living cells where to attach. The new technique also holds promise for sensor technology: A tiny three dimensional “lab on a chip” could be created, in which accurately positioned molecules react with substances from the environment.
“3-D-photografting” is the name of the new method.

Applying Sunblock - Visible vs Ultraviolet Light
Seeing how the lotion has different visual properties in different light - via Life Pixel
Sunblock being applied to face in visible light & ultraviolet UV light. As you can see this sunblock absorbs UV light rays and therefore appears to be black in the UV only video. In visible light it looks like ordinary lotion.

Water Light Graffiti
Interactive outdoor installation features big wall of LEDs which light up in the presence of water. Put together by Antonin Fourneau for DigitalArti. Video embedded below:
Water Light Graffiti by Antonin Fourneau, created in the Digitalarti Artlab from Digitalarti on Vimeo.
The “Water Light Graffiti” is a surface made of thousands of LED illuminated by the contact of water. You can use a paintbrush, a water atomizer, your fingers or anything damp to sketch a brightness message or just to draw. Water Light Graffiti is a wall for ephemeral messages in the urban space without deterioration. A wall to communicate and share magically in the city.

Sunlight Graffiti
Part of the Little Sun project by Olafur Eliasson currently running at the Tate Modern, where participators can create their own light graffiti and locate it online via an interactive sphere:
The Sunlight Graffiti sphere is by artist Olafur Eliasson, conceived as part of his larger Little Sun project. Little Sun, a work of art that works in life, is a solar-powered lamp that Eliasson has developed with the engineer Frederik Ottesen. The lantern is one element of the artwork, but the way it connects us and what it tells us about energy and energy access is all part of the art.
Currently, an interactive Sunlight Graffiti installation is set up at Tate Modern, London, on level 2 as part of the museum’s Poetry and Dream exhibition (28 July – 23 September 2012). Visitors are invited to do a work of art here by dancing, jumping, and writing out loud with a Little Sun in their hand. Their Sunlight Graffiti are captured and uploaded to this site and shown as part of the sphere.
Also presented at Tate Modern is Eliasson’s new artwork Your light movement, 2012, a video about physical movement, light, and life. Watch it here.
‘For this project at Tate Modern – the former power station turned into a museum – I have thought a lot about light as something that is more than just a means to illuminate something else. Light generates action. The Sunlight Graffiti project has been developed to foster human creativity and movement, driven by the power of light.
Little Sun responds to the situation we face today, where natural resources no longer abound. Energy shortage and unequal energy distribution make it necessary to reconsider how our life-sustaining systems function. I see Little Sun as the wedge to open up this urgent discussion from the perspective of art, to raise awareness about the need to improve energy access and the distribution of energy today.’

MAZE by Mabonona
Big neon circuit boards by Hangzhou-based artist - via neochaEDGE:
The word Maze has multiple meanings. Mabonona thought that “We are super relied on electronic products now, just like a disabled man rely on his fake leg.” However, ” We nearly know nothing about them”. He tended to show this contradiction and insecurity in the essence of the time, electronic chips. This complicated and surreal electronic “Maze” in front of us, reminds us to ask how much do we really know about the world we live in.
