Walk around the place du Molard in Geneva, Switzerland, and you’ll be walking on stars. Two thousand LED light sources equipped with 10 000 white Power TOPLEDs have been set into the paving stones. As the sun begins to set, the LEDs begin to shine, giving the square a magical aura.
When the Place du Molard was renovated, it was paved with cobble stones, identical to those which one already finds in the city center. Two thousand resin paving stones have been set in between, covering half a percent of the surface of the place. At nightfall the LED illuminated paving stones begin to shine, reproducing the shine and the silver-colored reflections of the Lake Geneva. The illuminated paving stones accumulate when approaching the lake and remind at the twinkling water, which penetrated up to this place in former times.

The two thousand resin paving stones are lucent during daytime, but become luminescent at nightfall. On each of the cobble stones simple words of everyday life are engraved, for example “hello”, “good night” or “welcome”, written in nine languages and symbolizing the multi-cultural character of Geneva. This installation underlines the pedestrian character and the history of the Place du Molard. Moreover the place takes account of the needs of the various users, such as pedestrians, tradesmen, florists, café owners and their guests.

Vierunddreißig Aktionen von Hans Nevídal
vom 10. Mai 2000 bis zum 10. Mai 2033 (jeweils 22:00 Uhr) an den Fassaden der Deutschen Nationalbibliothek

Am 10. 5. 2000, etwa zum Zeitpunkt des Autodafés vom 10. 5. 1933, begann der Wiener Künstler Hans Nevídal mit Projektionen von Brandschutzfilmen an die Außen wand der Deutsche Nationalbibliothek in Frankfurt. 2001 wurde diese Aktion an der Deutschen Bücherei Leipzig weitergeführt. 2002 fand sowohl in Frankfurt wie in Leipzig eine Aktion statt, wobei in Leipzig alte 35mm-Brandschutzfilme aus den DDR-Beständen der Feuerwehr Leipzig gezeigt wurden. Seither wird alternierend oder an beiden Orten gleichzeitig projiziert. Dieses Jahr zeigt Nevídal in Leipzig den Film » THE ART OF FIGHTING WILDFIRES / techniques, awareness, training«.

Inspired by the theme “The Green Man” architecture students Manuel Kretzer and Hans Sachs designed “The Cone”, an accessible dynamic structure. At night 700 LEDs from OSRAM Opto Semiconductors turned “The Cone” into a shining, rotating sculpture, visible from almost every point of the festival. The sculpture was built with two cones made of PVC-tubes, which were set on top of each other with the outer cone designed to rotate to create energy. The 8 meters high interior cone was mounted stationary on the platform and the 9 meters high exterior cone was fastened to the interior cone. Through the use of wind energy and human force the rotating sculpture produced energy for the nocturnal illumination.

The sculpture was illuminated by 700 green 5mm LEDs emitting light into the PVC-tubes. Reflectors were used to achieve the required narrow radiation. At night visitors to the interior of the sculpture could admire the fascinating effect of the overlap of the rod structures and the resulting continuous dance of shadow plays and light.

LEDs from OSRAM Opto Semiconductors were chosen to illuminate the artwork due to their robust nature and bright illumination. Moreover their small size made the LEDs ideal for the coupling into the PVC-tubes. During the festival the LEDs had to withstand temperature changes from 5°C at night to up to 45°C at noon. Heat, sandstorms and heavy winds were also challenges.

The “Burning Man Festival” is one of the largest art gatherings in North America. Each year at the end of August the festival takes place in the Black Rock Desert in Nevada, approximately 150 km north-east of Reno. In 2007 more than 45,000 people erected the 16km2 large artificial Black Rock City, which disappeared at the end of the festival without a trace.

In die Fassade der 2008 neu eröffneten Konzernzentrale der Energie AG Oberösterreich wurden 665 weisse geschoßhohe LED-Stäbe eingelassen, von denen jeder einzelne direkt ansteuerbar ist. Die Anordnung der Leuchten orientiert sich an der Struktur der Fassade. Unterschiedliche abstrakte Lichtanimationen übertragen die unregelmäßige Struktur der Fassade in die Ebene der Zeit. Das Gebäude wandelt sich in der Dunkelheit zu einem überdimensionalen Display, zu einer bewegten, abstrakten Lichtskulptur.
