Set-up

An eight-meter-high monolithic object was situated at the end of a twenty-meter-long mirrored walkway. Facing the walkway and embedded in the monolith is a format-filling LED screen. 

Applying an array of infrared cameras in order to track the people moving on the walkway, we converted this data using the vvvv system and a Max/MSP patch, so that it controlled the visuals and the sound.

Stepping onto the walkway triggered a bright impulse and walking from end to end shifted the visuals through the entire color spectrum. The number of participants controlled the complexity and depth of the installation on both the visual and the auditive sides.

Aesthetics

With the visuals, we played with the perspective of the rectangular, colored and pulsating arches visible in the screen, so that as more visitors occupied the walkway, more rectangles appeared and stretched along the z-axis.

This effect, in combination with the reflection in the mirrored walkway, created the illusion of floating in space and moving through a portal, into a room with infinite depth.
