ALEPH

aleph3

“On the back part of the step, toward the right, I saw a small iridescent sphere of almost unbearable brilliance. At first I thought it was revolving; then I realised that this movement was an illusion created by the dizzying world it bounded.” — Jorge Luis Borges

(dutch version below)
The Aleph, as described by Jorge Luis Borges in his text “El Aleph” (1945), is a (meta-)physical point, in which one can see the entire universe, from every angle, at the same time.

I have used this metaphor to visualise my memory. In ALEPH I’ve tried to capture the past four years of this study through the collection of photographs I took (1000+) during this period. Each photo has been individually tagged with associations and a perspective, so that in much the same way as I construct mental images in my head, this installation synthesises dynamic images from a given association. These images are presented as mini-Alephs, or sub-Alephs of the greater Aleph of my memory. And that in turn can be browsed by anyone else based on perspective or association. The project was inspired by the (im-)possibilities in representations of the memory, as it is by the (un-)attainable ambition of visual art to represent a reality in a reduced number of dimensions.

Made in OpenFrameworks (the Aleph itself) & Processing (for a perspective & associations saving tool). Frame: 120x120cm, wood, glass, projection.

De Aleph, zoals beschreven in “El Aleph” (1945) door Jorge Luis Borges, is een punt waarin het gehele universum te zien is, vanuit elke hoek, tegelijkertijd.

Ik gebruik deze metafoor om de werking van mijn geheugen te visualiseren. In ALEPH heb ik de afgelopen vier jaar op de academie proberen te vangen, waarbij mijn foto’s (1000+) staan voor de herinneringen aan de academieperiode. Elke foto is individueel van associaties en een perspectief voorzien, en op eenzelfde manier als dat ik beelden zie in mijn hoofd synthetiseert de installatie dynamische beelden— mini-Alephs— bij een gegeven associatie, en stelt hij het publiek in staat dmv. een verandering van perspectief mijn associaties bij dit beeld te verkennen. Het project is tot stand gekomen gebaseerd op de (on)mogelijkheden in de vergelijking tussen digitale geheugens en het menselijke, en de (on)mogelijke ambitie van visuele kunst (en het kubisme in het bijzonder) een werkelijkheid in een gereduceerd aantal dimenties weer te geven.

ABOUT THE PROCESS

Still combining perspectives 01

This project was the result of a long research process that took off in the autumn of 2010 with the question of how a digital memory would look like, versus a current state of a digital environment. This idea was rooted in several previous projects that touched either the subject of memory, or a fascination of a virtual environment. (Object Oriented, Comment Condensator, Perspective Print) Gradually, my interests shifted towards visualising the process of memorising through contemporary machinal metaphors and, at the same time, the problem of having too many dimensions to display. Digital assemblages of snapshots and perspectives…
I took inspiration from the quite interesting popsci books of Douwe Draaisma, the pioneering Cubists from the previous century as well as Archigrams Temple Island project.

ESCAPE

ESCAPE @ Expo Arnhem

ESCAPE

How do you experience a digital landscape?

ESCAPE is a room projection installation that immerses a visitor through four walls of projection surface. It transforms aroom into a virtual great glass elevator, vertically transporting spectators through an unlimited sequence of generative landscapes. Escape will be a study on the definition of ‘a digital landscape’. We will explore what elements constitute a landscape, and which qualities are required for immersion.

The project consists of multiple layers; static, dynamic, and interactive; a general narrative and cycle length (5 mins) has been defined, accompanied with a precomposed soundtrack (by Charlie Berendsen). Based on this narrative, landscapes are generated, color ranges shifted, special effect probabilities set and generative soundscapes blended on top of the soundtrack. Finally, the visitor is given control over the vertical navigation through these landscapes.

ESCAPE is conceived, produced and presented in collaboration with Charlie Berendsen.
Made with Processing, Reason & Pd-extended (audio)

What’s happening behind the scenes?
One master computer is reading values from a pre-composed timeline, values that are converted into generic ranges mapped to a specific time. Every instantiation of a new ‘scape’ by the master has set a position within this range. Changing the elevator’s position allows for new scapes being created, exploring the variation as dictated by the current range (which in turn is set by the timeline).
The parameters of the scape are then sent to four networked slave computers that render the same scene to each screen from a different perspective, and with certain degree of individual freedom in rendering mode—again as set by the timeline. A fifth slave also listens in, but translates these parameters to sound scapes and noise fields. This sound slave also triggers the soundtrack that goes along the timeline narrative.

Textbook Covers: Getal & Ruimte

Getal & Ruimte

LAVA Graphic Design has asked me to help develop a series of book covers for the Mathematics branch of EPN Education called Getal & Ruimte.

I was asked on board to develop the project in Processing after this was judged to be the tool for this job. We explored several formulae and printed out the results of 1000+ different combinations of parameters. From these in turn series were selected to be used for the different learning paths. In addition, we introduced different families for the different math subsets that were represented by the books. As extra gimmick, the formula used for each cover was printed on the book, so students can recreate the shape on their (graphical) calculators.

Download now: Apps (Processing)

While recovering from all the food I stuffed myself with during christmas, I documented some old projects and realised it might be fun to post their functional, interactive prototypes on the blog for anyone interested to download. Some projects just need playing with. :-)

They come as .app (mac) & .exe (windows) executables and should run straight out of the box (if you have Java installed, which you most probably have)

Mathematical Type
Download: Windows / Mac

Less tight

First a sneak peek, a brand new little app as the newest member of the Mathematical Typography series. It’s a fun experiment with interactive typography.

Time Surface
Download: Windows / Mac

This app revisits last year’s project which was about a three dimensional representation of an interactive calendar. This app uses offline bogus data, while the real thing aggregates from an online RSS source. Seeing the objects gradually break the surface of ‘now’, spin the lot around and performing some casual time travel definitely is part to the experience, so please have a go.

Object Oriented
Download: Windows / Mac

This prototype refers to another project finished last summer. It sketches a 3D node structure which is constructed through the structure of a text; paragraphs, sentences, words, letters.
Although this app has also being posted to OpenProcessing, downloading this adds some performance & lets you run it full screen. Which I think is nice. Fact remains that you can see and download the source online here.

Sadly no fancy iPhone apps yet, although I’m currently in the process of making my first (!)

Abstract Life

Birdlife-9313

Birdlife-4175

Birdlife-3018

This was an attempt to create a ‘meta-documentary’, by tracing original nature documentaries using OpenCV and representing the result as a documentary of its own, based on ideas presented in Philip Ball’s popsci book “Critical Mass”, covering historical research on finding mathematical laws for social behaviour.
I have rendered the images with Processing, and edited afterwards in Final Cut Pro. Although the original camera work & cuts provide most of the dynamics.

Object Oriented

Text Universe | OpenProcessing.org

Text 02 | Distribute

2030: Envision a world in which every object would have an ‘online’ identity, a digital representation, say– a facebook page. Every physical object would be reduced to its properties, be it value, energy usage, lifetime, color, previous owner, parent class or atom arrangement. A concept quickly getting abstract beyond the point of no return, hence this sketch visualizing the concept using a structure that would represent ‘the digital genome’ of the real world. A structure that would contain the digital avatars of all physical objects.

For this, I used as placeholder a text, dividing it’s hierarchy into branches of objects. Each node in this structure should represent a physical object, with it’s properties attached. In this case, a chapter of the book “The Dark Tower”, by Stephen King has been chopped up. The text comprises of paragraphs, each paragraph contains sentences, sentences often are compilations of subsentences and all these consist of words. And words of letters.

This framework of nodes should represent the idea of the world as a collection of objects, as information is attached them. Every object has a parent, from which it inherits certain properties, and has other ones that make it unique.

Sound Portraits

Sound Portrait: Serkan

Last few days were pretty much about OFLab Breda, an OpenFrameworks workshop by Zach Lieberman & Todd Vanderlin. With the technical guidance of Zach & Todd we were encouraged to develop a project in these few days that was to be exhibited at the Graphic Design Festival. Along with the festivals theme “DECODING” the Arnhem team consisting of Jasper van Loenen, Bart van Haren and Sander Sturing came up with the idea of transmitting data by sound, hence making the transmitting process physical. Background noise and sounds from the environment provide distortions and artifacts.
Other than the live installation, we presented the project as a series of “Sound Portraits” portraying several of the Lab’s participants.

OFlab Breda: Sound Portraits

Among the participants portrayed are Takayuki Ito, Emily Gobeille, James Acres, Zach and ourselves.

Sound Copy: Listening in class

It took three hours to send the image data through sound to the laptop depicted above. The image shows the environment that is hardcoded in the image by the laptop on the table, listening. The colors show recorded sound that’s outside of the spectrum that is used to send the image data. The image has been built up gradually from left to right, top to bottom.

Sound Portraits is a collaboration project of Jasper van Loenen, Bart van Haren, Sander Sturing & myself.

Colour of Motion in NEMO Amsterdam

I think it’s safe to announce the exhibition of the 2008 Colour of Motion project in the form of a video installation in Science Center NEMO Amsterdam. The installation will record live on the first floor, and project on a single broad screen.

I’m really excited to see it working. I believe Theo Watson said one of the biggest compliments an interactive installation can get is that children start playing with it without the need of an explanation. The environment of NEMO should be ideal to see this tested. Fingers crossed!

The installation will probably be running in April.

Mathematical Typography

I’ve gone astray experimenting with math & typography. For each specific math subject I try to create a family of type renderings.

Basic geometry, “spatial relationships”:
Specific colors correspond to the the angle of the 20 million lines drawn.

Printed it! ;)

Trigonotype:
The type is constructed out of a lot of translated (co)sines.

Along each point of the outline of this Helvetica, a line is drawn according to it’s tangent.

TodaysArt 09: Typographic Gun

Typographic Gun @ TodaysArt 09

At the TodaysArt festival at the Hague the public library features an installation we developed along the lines of the festival’s “conflict” theme. During the night hours, we project on the windows an aggressive dreammachine-like flickering.

Typographic Gun

Since the very moment paper press was invented, type has been a weapon, with paper being the battleground. The recent shift towards digital media has expanded and intensified the written warzone even further.

The audio-visual installation named ‘Typographic Gun’ explores the subjective potential of the written medium. The library becomes the epicenter of a conflict between two opposing texts, opinions or ideals. The subjectivety is hidden behind interpolating typography, alternating at 5 to 20Hz, melting the two channels together, but at the same time generating the conflict by means of anticolors and after image. Any spectator can choose to block out any of the information streams by means of a color filter. And every book that has been loaded into the system produces its own unique soundtrack, converting sentences to a rythm of microtonal sound that add to the conflict experience.

Project: Human Nature (VU Amsterdam)

Human Nature (Zuidas)

Human Nature (Zuidas)

In collaboration with Architecture History students from the Vrije Universiteit Amsterdam we were asked to develop a cultural comment on the urban development in the Amsterdam Zuidas. This area, originally meant as an commercial district, was now been made ready for residents. Our projects should be part of the gentrification process.

But all culture aside, I was fascinated by the way nature was treated on the Zuidas. The planners of the Zuidas had given shape to the most modern view on the relationship between man and nature– and I can tell you, it’s interesting to say the least.

One example that triggered me were the trees on the Zuidplein. Originally, there weren’t any. But as unpleasant drafts developed along the square and inside the underground bicycle parking, soon it was decided the square needed trees in order to solve this turbulence. Only problem was, that with this underground parking there was no soil to plant them in.
And this was then solved by installing 40 massive 3 cubic meter concrete flower pots for each tree. The soil in those planters is monitored by sensors which are wired to a computer that directly controls the watering of the pot.

Inspired by this example I pitched the concept of abstracting nature by indexing it on its functionality only.
I teamed up with Sander Sturing from my class, and Martijn van Beek and Niels Bakker from the VU who provided us with the historical context. We started to develop a way of navigating this environment. Artificial and natural objects were indexed on their capacity to fulfill our specific needs and entered into a database. This video documents an installation we used to visualize the concept of abstracting nature by indexing it on its functionality only. An extreme point of view, taken to highlight the level of cultivation the new to be cosmopolis of Amsterdam, the Zuidas, aspires.
