I was recently at a workshop / residency at the Mapping festival 2010, Geneva, Switzerland. Many collaborators, artists, musicians, performers, visualists took over various spaces at La Parfumerie to create audio-visual performances and installations. Constructing a large scaffold structure in the main hall, armed with DMX controlled lights, microphones, cameras, sensors and projectors; we converted the space into a giant audio-visual-light instrument for the audience to explore and play with, and be part of and experience a non-linear narrative performance. The project involved live projection mapping, motion tracking, audio-reactive visuals, piezo-reactive audio and visuals, DMX controlled lights, rope gymnasts, acrobats and much more!
I designed and programmed visuals (projections) for the OKGo performance and Fendi installation at Design Miami 2009. OKGo were playing modified Les Paul guitars mounted with laser beams in the headstock, designed by Fendi in collaboration with Moritz Waldemeyer. Using a PC equipped with a high-speed firewire camera, I developed custom software to track the laser beams and generate visuals around the spots they hit the wall. These visuals were also audio-reactive, responding to the live audio feed coming from the sounddesk.
More images & video coverage coming soon.
P.S. For additional laser tracking goodness, checkout the Graffiti Research Lab's Laser Tag.
Inspired by the brilliant use of an age old concept in the recent OKGo 'WTF' video, I created this little open-source demo in processing. It works in real-time with a webcam and you can download the app and source from http://www.msavisuals.com/xmas2009
"Reincarnation" is an off-shoot from a visual performance for the Rambert Dance Company's "Iatrogenesis" at the Queen Elizabeth Hall, South Bank, London UK - visuals for the latter directed by my good friends at flat-e.
The project began when I started working with footage of the Rambert dancers. Inspired by the footage, I wrote custom software to track the motion and generate the visuals you see in the video below... and "Reincarnation" was born.
For the Rambert's "Iatrogenesis" piece, I created similar visuals, abstract visual layers containing subtle hints of human forms and motion, which would tie in with the movement of the dancers on stage. These were used by flat-e and composited with various other layers and projected on a see-through gauze in front of the stage.
The video (and music) you see below is not representative of the visuals (and music) of the Rambert's and flat-e's "Iatrogenesis". This is just a standalone piece born from working with the Rambert choreography.
When the clip starts, you probably won't recognize a human shape at first, but your eyes and mind will be searching, seeking mental connections between abstract shapes and recognizable patterns, like looking for shapes in clouds. You'll be questioning what you see, is that it? is it sitting? is it crouching? is it kneeling? Then all of a sudden, it'll be crystal clear. Then you'll try and keep it in focus, following it as it moves around, tracking each limb, using the motion to construct an image of the parts you can't see. It'll fade in and out of clarity. At times you'll be clinging onto just the tip of it's hand swinging round, trying to identify any other recognizable parts. You might see another arm or leg and grab onto it, fighting not to lose it. Then it'll be crystal clear again, and then all of a sudden vanish, literally in a puff of smoke, and your eyes will start searching again.
Working with Seeper, we created a vision driven interactive stand for Brandwidth and Toyota IQ. The stand is touring shopping centers in the UK and currently at the Westfield Shopping center in London.
I'm delighted to announce that my "Gold" installation has been selected to be shown at the Tent London exhibition as part of the London Design Festival. 24-27th September 2009, at the Truman Brewery, London, UK. Stay tuned for more information.
The video below is an early demo of the installation.
“Gold” is an interactive installation which explores our obsession with super-stardom, and the extravagance that accompanies it. Through a ‘magic mirror’, revel in a world of excess where you are the super-star. Shower in glittery gold, experience almost omnipotent powers as you materialize, morph and dematerialize into pure sparkling gold dust. Immortalize yourself as a shimmering golden statue, before you collapse and fade away.
The installation uses custom software written with openFrameworks and the OpenCV computer vision library. The software analyzes the video feed from infra-red cameras in real-time and generates 1080p HD output using OpenGL.
Working with Arnold Agency and Todd Vanderlin+Ryan Habbyshaw from their R&D team, we created an interactive display for Citizens bank in branches in major cities in the US.
Using motion tracking, the pedestrians can interact with the display, signaling birds to come flying in and drop coins, grow plants, create wind to blow the plants around and spray pollen etc. The display is also time-reactive, automatically theming itself depending on time of day.
This is a demo of projection mapping with VDMX & Quartz Composer inspired by deepvisual's tutorial of doing it in modul8 (uk.youtube.com/watch?v=2bRfdn9lNO8).
VDMX unfortunately doesn't have this feature built-in, but fortunately has beautiful integration with Quartz Composer - allowing me to build a quad warper in QC using a GLSL vertex shader, which should be super fast.
Also, around the 4:30 mark you'll see me masking the video on the box in the back. This is also using a custom Quartz Composition which allows 4 point mask creation. Usage is almost identical to the QuadWarper, but instead of warping the image it just applies a mask, or you can invert the mask and it cuts a chunk out. You could do the same by creating new layers, grouping, using as a layer mask etc. but its a a bit more hassle I think. Using the QuadMask is a lot quicker and you can put multiple QuadMasks on the same layer to draw more complex masks.
I was fortunate enough to be part of the OF Lab team this year at Ars Electronica in Linz, Austria.
Apart from building a 3 storey lab, tons of random little bits of software and visualizations for our environment, we also had the challenge of creating pieces inspired by 5 words submitted by the public - with only a few hours upto a day per project.
Below is an excerpt from "one second before big bang". Visuals all realtime and purely controlled by motion.
"Roots" is an interactive musical/visual installation for the Brick Table tangible and multi-touch interface, where multiple people can collaborate in making generative music in a dynamic & visually responsive environment. It is a collaborative effort between myself and the Brick Table creators Jordan Hochenbaum & Owen Vallis. It will premiere at the Minitek Music + Innovation Festival September 12-14, 2008 in New York.
The essence of the interaction, is that you control parameters of a chaotic environment - which affect the behaviour of its inhabitants - which create and control music.
To breakdown very briefly without going into much detail:
There are vinelike structures branching and wandering around on the table. They live and move in an environment governed by chaos.
Audio is triggered and controlled entirely by how and where the branches move.
You - the user - control various parameters of the chaotic environment. Parameters which range from introducing varying amounts of order, to simply changing certain properties to let the chaos evolve in different directions.
There are varying levels of interaction, ranging from traditional one-to-one correlations - 'this movement I make creates that sound', but also to more complex relationships along the lines of 'this movement I make affects the environment in this way which sends the music into that direction where it evolves with a life of its own'. The visuals are purely generative, as is the audio, and as user you can play with the parameters of that system and watch and listen to the results...

"Pi" is an interactive audio/visual installation commissioned by Trash City of the Glastonbury Festival to be shown at the festival in June 2008.
Working with arts and technology collective Seeper, our concept was to take a 50ft tent, and convert it into a giant audio/visual instrument - all of the music, audio and visuals inside the tent are generated and controlled purely by the movements of the occupants.
The space was divided into 6 zones. Two of the zones were purely visual, this was the waiting area. Here people could dance, chill, run about and do what they pleased. Two cameras tracked their movement and applied it to the fluid/particles visuals - so people could 'throw' plasma balls at each other, or send colorful waves propagating around the space. The other 4 zones had the same visual interactions, but in addition were also connected to an audio system. Each of these four zones was allocated an instrument type (drums/beats/percussion, pads, bass, strings etc.), and movement within these zones would also trigger notes or beats - depending on precisely where in the zone the movement was triggered. A lot of effort went into designing the sounds and notes triggered to make sure the end result would almost always sound pleasant and not be complete cacophony.
The first psychedelic fluid/particles interaction prototype developed in processing.org:
Camera -> osc/midi interaction tests (developed in Quartz Composer):
The two concepts strung together and written in C++ with openFrameworks:
This is a little teaser for an audio visual interactive installation I'm working on for Glastonbury 2008. It'll be projected around the entire (almost) 65ft interior of a 50ft round tent with multiple channels of audio. Everyone inside will be contributing to the audio/visual experience. Located behind the Laundrettas' crashed plane / laundrette in Trash City.
All visuals and music is entirely camera driven (by my waving arms and hands) and real-time. Originally started this app in Processing, but realized I needed as much power as possible so switched to C++ / openFrameworks. Not using the GPU as much as I'd liked due to time restraints, v2 will be fully GPU hopefully ;)
This is the beginnings of a Processing / Java port of the webcam-to-osc/midi app I originally did in Quartz Composer. The source code for the processing version is below, and you can watch (or download) the Quartz Composer version here).
Its quite early days yet and doesn't have all the features I want (scales, realtime sizing of grid etc.), but I'm posting posting it because:
a.) it does work on a basic level,
b.) It was requested on the processing forums and I thought it might be useful...
It doesn't transmit midi, but does transmit OSC, and I'm using OSCulator to forward the OSC messages to midi. I prefer doing it this way because I can have another computer on wifi receive the OSC messages and map to midi (and send to Logic), keeping the CPU on both machines lighter... (or just keep the oscTargetIP as 127.0.0.1 to send the OSC to the same machine and have everything running on one machine. Flexibility is always sweet).
Aldeburgh Music is an organization based in Suffolk, UK working with musicians - both professional and just starting out - to help them reach their full potential by providing them with the time and space to discover, create and explore - as well as providing inspirational scenery and a rich musical heritage.
The New Music New Media / Britten–Pears Programme offers advanced performance experience to young professional musicians in the inspiring surroundings of Snape Maltings, home of the Aldeburgh Festival founded by Benjamin Britten in 1948.
A test in motion detection in Quartz Composer 3.0.
The music is all generated in real-time by me waving my fingers, hands and arms around (or in fact any motion) in front of a standard web-cam. No post-processing was done on the audio or the video.
The concept is by no means new, but still fun nevertheless - and I'm quite happy with this implementation. I'm using a very simple frame difference technique and generating midi notes based on where-ever there is movement (actually, as QC3 cannot send midi notes I had to send the data as OSC and use OSCulator to forward them as midi).
