Letzter Atemzug
Ich verstehe passive Instrumente als verschiedene Multimedia-Objekte, für die weniger Management als Koexistenz erforderlich ist, basierend auf Beziehungen, die aus einer gegenseitigen „hybriden“ Symbiose hervorgehen. Das Funktionsprinzip des Objekts ist recht einfach: Die ausgeatmete Luft (ihr Druck und ihre Durchflussrate) aktiviert den generativen Prozess, der von den Ausatmungsparametern abhängt und von der Luftbewegung im Organ gesteuert wird. Das Objekt erfordert keine spezielle Spieltechnik, obwohl jede Änderung der Atmung (entweder vorsätzlich oder durch physiologische Faktoren verursacht) direkt von der Spieldynamik und auch von allen anderen Parametern abhängt, die zur Erzeugung des Schallflusses verwendet werden.


Until I die
This installation operates on unique batteries that generate electricity using my blood. The electric current produced by the batteries powers a small electronic algorithmic synth module. This module creates generative sound composition that plays via a small speaker. The blood used in the installation was stored up gradually over 18 months. The conservation included a number of manipulations to preserve the blood’s chemical composition, color, homogeneity and sterility to avoid bacterial contamination. The total amount of blood conserved was around 4.5 liters; it was then diluted to yield 7 liters, the amount required for the installation. The blood was diluted with distilled water and preservatives such as sodium citrate, antibiotics, antifungal agents, glucose, glycerol etc. The last portion of blood (200ml) was drawn from my arm during the performance presentation, shortly before the launch of the installation.


last breath
I understand passive instruments to be different multimedia objects that do not require management so much as co-existence with them based on relations born of a mutual “hybrid” symbiosis. The operating principle of the object is fairly simple – the exhaled air (its pressure and flow rate) activates the generative process, which depends on the exhalation parameters and is managed by the air movement in the organ. The object does not require any special game technique, although any change in the breathing (either premeditated or caused by physiological factors) is directly dependent on game dynamics and also on all the other parameters used to generate the sonic flow.

your unerasable text
“your unerasable text” is an interactive installation, dealing with the topics of data storage and elimination of data. The installation can be placed in an exhibition, but ideally it’s exhibited in a public space window, where it can be used by people passing by 24h a day. The participant is asked to send a textmessage to the number written on a sign next to the installation. “send your unerasable textmessage to +43 664 1788374”. The receiver mobile transfers it to a computer, which is layouting the message automatically. Then it is printed on to a DIN A6 paper, which is falling directly on to a papershredder. There the message remains readable for a few moments and gets destroyed then. The shredded paper forms a visible heap on the floor, which reminds of a generative graphic.

“A collaboration with Symmetry Labs at Gray Area Foundation for the Arts in San Francisco. Derivatives of multiple generative rules I designed in the past were adapted to an interactive LED floor. The video demo includes 6 visual sets and transitions in between. Set 01 is an adaption of 1DFBD, which was also used in a couple of projection mapping tests in 2014. Set 03 is derived from an untitled turbulence piece created in 2014 as well. Similar to Set 03, all agents in Set 04 are driven by 3D Perlin Noise flow field. However, instead of being an emitter spawning agents, each dot functions as an attractor intervening in the flow, same way as it did in 2BCD.”Raven Kwok
