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 the title of a custom-made interactive installation that brings forward audiovisual
forces by interacting without physical contact, using your hands.
An interactive instrument, using algorithms created by looking at the moment of
real life tornado´s, the installation produces light, sound and animation, which can be further controlled
through custom-made functionality - controlled with turnable knobs.
The installation functions as an interactive, audiovisual instrument, based on the classic Theremin.
The theremin, originally known as the etherphone, is an electronic musical instrument controlled without
physical contact by the thereminist (performer). It is named after the Westernized name of its Soviet inventor, Léon
Theremin, who created the device in 1928.
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. The
electric signals from the theremin are amplied and sent to a loudspeaker.
Sonic Tornado is based on the principle of the theremin, using the position, movement and shape of your hands
to evoke and control audiovisual forces: Light, Sound and Animation.
The installation recognises handmovent, each hand and each finger can be used to control diffrent movements,
animations and sounds within the installation.

Sonic Tornado´s algoritm is based on the innerworkings of reallife Tornado´s.

Sonic Tornado got its name from the algorithm inside the installation which determines the
movement for the sounds, lights and animation, in response to users movements.
Intense swirling of movement and quadraphonic sound increases over time when being used or set in motion
by the installations user(s).
The tornado evokes a chaotic twirling force that generates light, sound and animations when used.
The installation plays with supernatural powers, in an audiovisual universe where there forces are under your control.
The parameters can be set and 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 with flickering 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.
