A white vortex pulsating in a cylinder of light
A cylinder of light stands on a barge floating in the water.
Moving air, contained in the glass cylinder, circulates in a closed system causing a vortex to form.
White water vapour, acting as a signal material, is caught in the light and reflects how the air moves and dances.
The dancing of the vortex is caused by electronically varying the speed and flow of the air in the system.
