Ateneum landing, 3rd floor
Kai van der Puij: 11.5 Hz
Address: Kaivokatu 2
11.5 Hz is a study of how to create a variety of light-based shapes by turning a skipping rope. Onlookers will be bewildered by the moving chord of light and the two balls of light it draws in the air.
The fibre-optic cable will be spun by an electric motor, whose speed is adjusted by a frequency converter. The shape created will depend on the rotation speed. The frequency selected for this work is 11.5 hertz, which corresponds to a rotational speed of 345 revolutions per minute.
Since this minimalist work requires space around it, Ateneum will provide the installation with the setting it deserves. The third-floor landing can be reached by walking up the stairs of Ateneum's main lobby. The work can be seen at the museum without paying an entrance fee.
The exhibitions of Ateneum Art Museum, including the Henri Cartier-Bresson exhibition, are open during the festival from 10 am to 8 pm (tickets 13/11 €).
The work featured in the Design Forum Showroom, which was part of the Lux Helsinki additional programme in 2015.
