ΔIRPLΔY

At sunset on September 23, an art performance by Sabine Kacunko took place in the “Lustgarten” on the UNESCO World Heritage Site “Museumsinsel” in Berlin, Germany.
ΔIRPLΔY was a 600-watt single beam emitted by an RTI ANGO 600 that was emitted vertically into the stratosphere. The color of the laser projector displayed the on-site air quality currently being measured.
The spectators present on site were able to change the laser color by using a specially developed app and by breathing out the inhaled air into their smartphones. ΔIRPLΔY thus made the interaction of breathing and air movement directly visible. The vital function of inhaling and exhaling thus created a fundamental connection of breathing living beings to their planet. ΔIRPLΔY is playfully transformed into a vivid model of an expanded environmental awareness.

The RTI ANGO 600 was chosen for this art project because of the high power of 600 watts of the laser projector and the balanced individual outputs of the source colors, which result in a balanced and homogeneous color mixture even over long distances. Especially for this project with its changing color balances, this feature was particularly essential.
The RTI ANGO 600 emitted the single beam via a DMX signal generated by control hardware from LaserAnimation Sollinger.
For this, the control software communicated with the customer’s control system.

The ΔNIMΔ ΔPP (https://anima-web.de) allows an experimental handling of the exchange of global, local and individual air streams. On the one hand, it is based on current data from various research institutions (including the German Federal Environmental Authority); on the other hand, it relies on individual use: An extended color spectrum of 233 colors (a number from the infinite sequence of the Φ and the Fibonacci number sequence based on it) allows a refined interaction and interpretation of current and archived inputs.
