Part lightshow, part art piece, part exploratory technology, Light Barrier (third edition) by South Korean duo [Kimchi and Chips] crafts a visual and aural experience of ephemeral light structures using projectors, mirrors, and a light fog.
Presently installed at the ACT Center of Asia Culture Complex in Gwangju, South Korea, Light Barrier co-ordinates eight projectors, directing their light onto a concave cluster of 630 mirrors. As a result, an astounding 16 million ‘pixel beams’ of refocused light simulate shapes above the array. The array itself was designed in simulation using an algorithm which — with subtle adjustments to each mirror — “grew” the display so as to line up the reflecting vectors. Upon setup, final calibration of the display used Rulr to treat each ‘pixel beam’ as a ray in 3D space to ensure image accuracy once the show began. Check out a preview after the break!

[Blake Schreurs] found himself in dire straights — there was a critical lack of available hammocks in his immediate vicinity, and he wanted one. Fast. So he built a hammock stand in half an afternoon.
Initially dismayed by the cost of store-bought models, [Schreurs]’ hammock stand is perfect for woodworking-newbies and yard-loungers on a budget alike, as the build requires only a few straight cuts and some basic tools to whip up.
After cutting and laying out the lumber to make sure that it will all fit together as intended, [Schreurs] aligned and drilled holes through the pieces — don’t worry, he’s included the measurements in his post. Playing a game of connect-the-boards-with-carriage-bolts-nuts-and-washers — with a minor pause in the action to attach the feet to the base — all but finished this quick build. All that’s missing now is a hammock in which to recline!
One final note: be sure to use galvanized hardware for this — or any — project that’s expected to spend time out in the elements. Rust is not usually your friend!
Lounging in your backyard beginning to feel a little cramped? Take you relaxation on the road.
Teleknitting, the brainchild of Moscow artist [vtol], is an interesting project. On one hand, it doesn’t knit anything that is useful in a traditional sense, but on the other, it attempts the complex task of deconstructing broadcasted media into a simpler form of information transmission.
Teleknitting’s three main components are the processing and display block — made up of the antenna, Android tablet, and speaker — the dyeing machine with its ink, sponges, actuators, and Arduino Uno, and the rotating platform for the sacrificial object. A program running on the tablet analyzes the received signal and — as displayed on its screen — gradually halves the number of pixels in the image until there is only one left with a basic representation of the picture’s colour. From there, thread passes over five sponges which dye it the appropriate colour, with an armature that responds to the broadcast’s volume directing where the thread will bind the object.

Ah, the holiday gingerbread house. A traditional — if tedious — treat; tasking to create, delicious to dismantle, so why not try applying some maker skills to making the job of building it easier? [William Osman] decided to try two unorthodox approaches to the gingerbread construct; first, he opted to build a gingerbread mobile home. Secondly, he cut the pieces out with a laser cutter.
After the tumultuous task of baking the gingerbread sheets, [Osman] modeled the trailer in SolidWorks and set to work cutting it out on his home-built, 80W laser cutter. Twice. Be sure to double check the home position on any laser cutting you do, lest you ruin your materials. Also — though this might be especially difficult when modelling food in any CAD programs — be sure to account for the thickness of your materials, otherwise you’ll end up with a lot of trimming on your hands. At least gingerbread cuts easily.
Hot glue and royal frosting secured the pieces together — as well as some improvisation of the final details — making for a picture perfect holiday scene — from a certain point of view.

If only we had affordable artificial muscles, we might see rapid advances in prosthetic limbs, robots, exo-skeletons, implants, and more. With cost being one of the major barriers — in addition to replicating the marvel of our musculature that many of us take for granted — a workable solution seems a way off. A team of researchers at MIT present a potential answer to these problems by showing nylon fibres can be used as synthetic muscles.
Some polymer fibre materials have the curious property of increasing in diameter while decreasing in length when heated. Taking advantage of this, the team at MIT were able to sculpt nylon fibre and — using a number of heat sources, namely lasers — could direct it to bend in a specific direction. More complex movement requires an array of heat sources which isn’t practical — yet — but seeing a nylon fibre dance tickles the imagination.

How much access do you have to a 3D printer? What would you do if you had weeks of time on your hands and a couple spools of filament lying around? Perhaps you would make a two second stop-motion animation called Bears on Stairs.
An in-house development by London’s DBLG — a creative design studio — shows a smooth animation of a bear — well — climbing stairs, which at first glance appears animated. In reality, 50 printed sculptures each show an instance of the bear’s looping ascent. The entire process took four weeks of printing, sculpture trimming, and the special diligence that comes with making a stop-motion film.

The Amoreiras Tower, in Lisbon, Portugal, recently added a rooftop viewing area that is open to the public. The top of the tower is one of the highest spots in the city, and the viewing area gives an impressive 360º view of the surrounding area. However, the elevator to get to the top left a lot to be desired. It’s an interior elevator, and didn’t itself offer any view.
So, Artica, along with Schindler, were brought in to solve that problem. The solution was to mount displays on the interior of the elevator, in order to simulate a 360º panoramic view of the city outside. The video is synced up with the elevator, so the view changes as the elevator passengers move up and down between floors.
Artica, who was responsible for the concept, design, and electronics installation accomplished this by first building a prototype in their office building. This was a full-size elevator replica with which they could test the design and get it ready for installation. They then partnered with Schindler to actually install the system in the elevator of the Amoreiras Tower, which necessitated almost completely rebuilding the elevator. As you can see in the video, the resulting view and accompanying music (definitely not elevator music) are fantastic, and it was even done in time for the public opening of the rooftop viewing area.
Like us, you may be wondering where the video footage came from. The scene moves in apparent parallax so video was obviously captured with continuous motion and isn’t a scrolling image. This is the work of a camera toting drone.
