  Tornado´s are magnificent. Wouldn’t it be great if you can create one with your hands?  
     
  Sonic Tornado  
  Interactive Audiovisual Theramin  
 

Sonic Tornado is an instrument that brings forward audiovisual
forces that produce light, sound and animation.
Sonic Tornado´s algorithm is based on the innerworkings of reallife Tornado´s.
transformed to parameters that can be controlled through custom-made functionality.
Users can interactively control Sonic Tornado by moving their hands and fingers.
By recognising handmovent, each hand and each finger can be used to control diffrent sequences
of light, animations and sounds.

Sonic Tornado took inspiration from the classic Theremin: an electronic musical instrument invented in 1928 by
Leon Theremin, that can be controlled without physical contact.
The instrument's controlling section usually consists of two metal antennas that sense the relative position of the
thereminist's hands and control oscillators for frequency with one hand, and amplitude (volume) with the other.

Sonic Tornado evokes a chaotic twirling mass that generates light, sound and animations and lets its users
play with supernatural powers, in an audiovisual universe where there forces are under their control.
Intense swirling of movement and quadraphonic sound increases over time and gains intensity when set in motion.
The tornado can be played like an instrument, using only your hands, creating an explosive “big bang” of
audio visual forces.

 
     
 

 
 

 
   
 

 
   
   
  Sonic Tornado is completely intuitive, no text is required to use the installation.
When you enter a room you will see a control box with turnable knobs, a projected screen,
lights and sound speakers.
Once you move your hands over the box, the Sonic Tornado starts to work.
Your hand movements will generate light, sounds and animation.
You can control the speed, sounds, lights and animations by turning the knobs on the installation
and playing with the possibilities. The installation challenges you to play with its parameters.
 
  You, the user, can steer the direction and intensify the stream of animations and sounds, nested in chaos.
The turnable switches give you even more options for playing with sound, light and animation.
You can compress the tornado stream of animations together, or spread them apart, along with the music.
The sample slicer gives you the ability to make the sound and light samples longer or shorter.
You can create beats withflickering lights, or melodies with lamps slowly lighting up.
You are the composer of the installation, so it is up to you.
Surrealistic characters represent elements in the tornado, each carrying their own sound.
When you use the buttons to determine the size of the horizontal movement, you pull both sound and image
apart, when you use the vertical movement, you press the sound and image nearer to each other.
 
  Much like an Instrument, you will feel like you are playing a theremin: your hand movements for a composition of
light, sound and animation.
