Winter Sparks (part 2)
The Winter Sparks show at FACT Liverpool is small and efficient. Three large-scale installations that experiment with scientific phenomena and pay homage to Nikola Tesla. The works can be experienced without mediation but each of them also conveys several layers of meanings and readings, whether you're intrigued by the technical description or by the sheer beauty of the sparks, lightening bolts, and sonic properties of the works. Each piece in the exhibition also functions as both an art installation and a musical instrument that the artists played during the opening night of Winter Sparks.
I already told you about the Evolving Spark Network installation yesterday so let's move on to Alexandre Burton's Impacts, a work that demonstrates convincingly that you can still stun and amaze the crowd using a technology that was invented around 1891. The installation uses Tesla coil and a quick look at its wikipedia entry taught me that the electrical resonant transformer circuit is so popular that its enthusiasts show off their home-made Tesla coils at "coiling" conventions, that Björk used a Tesla coil as the main instrument in the song Thunderbolt, and that others use coils to play Mario Bros theme song.
Right before we approach the installation, we are advised that it's better not to go too close to the work -actually "Do not to touch!" is a better way to describe the warning, not to enter the room with a pacemaker, nor to let unaccompanied children in. Even mobile phones are not invited to the party as "there is a chance that the electromagnetic field emitted by the tesla coils could corrupt the flash or damage the memory of your mobile device or crash running programs."
The Tesla coils are activate by the presence of the visitors. As you go near, arcs of electricity of variable intensities come crashing against a glass pane. The violent flashes of light and sound are dramatic and fascinating, because of the lightning bolt patterns formed of course but also because you have the feeling of being in close proximity to danger.
With this new work, Alexandre Burton proposes the use of plasma (loosely defined as an electrically neutral medium of positive and negative particles) as matter and medium itself, circumscribed by a defined frame and articulated through unique programming. In this way, IMPACTS serves as a reminder of the danger and muscle of this marvel while capturing its sublime beauty and rhythmic potential.
Part physics experiment and part art work, the installation takes its cue from the Wilberforce pendulum, a spring hung on the ceiling with central and eccentric weights that alternate between two oscillation modes. Once calibrated, vertical and circular movements alternate even without additional external energy. It is an example of a coupled mechanical oscillator.
Bosch & Simons equipped the springs with audiovisual equipment that documents everything around the FACT Atrium. The video camera, microphone and loudspeakers capture sounds in the environment and in turn, generate visual and audio data that visitors can experience on a screen located in a dark room nearby.
