The idea is simple :
- the visitors turn the stucture that is hanged up by 3 audio ropes to the ceiling. The more they turn the cone the higher it gets.
- they get inside the cone
- the cone starts to rotate back, accelerates going down, it"s getting darker
- inside the cone their is a music sampler : they control the beat, tempo, pitch, some sound effects on a simplified interface.

The sound is coming from 2 speakers implemented inside the cone walls on two opposite extremes : the visitors are inside of a moving space-music. The beat is spacialized. The amount of light and the quickness of the rotation are changing and thrilling variables.

Now imagine the sensation of having a space turning around you, the beats are unlocalisable, the melody gives your head a spin, the light is changing all the time smoothly...
