    Interactive screen display for tade fair stand, 2008

    An interactive screen display was developed for the OSRAM stand at the light+building trade fair in Frankfurt in collaboration with ART+COM.

    Climate protection being the theme of the installation, each visitor is estimated to have the decision making power on over 1,540 tons of CO₂. This amount could be potentially reduced by implementing more efficient lighting. In order to emphasise the influence each individual has on the climate change, the number of trees necessary to compensate this CO2 emission is displayed.

    A tracking camera records the number of visitors who enter the OSRAM stand in real time. Every new visitor triggers the growth of a new tree in the foreground of the screen. As the number of visitors increase the tree thicket gets denser as well.

    The total number of viewers on one day, their CO2 saving potential and the corresponding number of trees are displayed on the top part of the LED screen.

    Light installation in an urban environment, 2007

    A new display for OSRAM Seven Screens in Munich was created on behalf of ART+COM, Berlin. OSRAM Seven Screens is an installation of seven double-sided vertical screens in front of the OSRAM main office in Munich, next to the highway “Mittlerer Ring”, one of the most congested roads in Munich and Germany.

    For the display Reactive Sparks, the traffic on the street is tracked in real-time; each vehicle creates a spark which moves across the screens. The Waves in the lower part of the display represent the amount of traffic in the past few minutes. More traffic results in higher waves with faster movement. The installation conveys the idea of energy and movement translated it into a visual representation. The warm colours create a warm spot in the gray winter landscape. The display will run until April 2008.
