Visitors to this installation in northern Denmark by German artist Thilo Frank are invited to walk through a contorted loop of timber while listening to the sounds of their voices and footsteps played back to them (+ slideshow).
A circle of concrete paving creates a continuous walkway, while 200 wooden frames with incrementally different dimensions provide the twisted structure surrounding it.
Microphones are hidden within the wooden beams and record the sounds made by everyone that steps inside.
These sounds are continuously remixed by a computer and played back through tiny speakers to create a distorted echo.
"The work acts as an archive of sounds and at the same time the visitors' perception of space and presence is amplified," explained Frank.
Light enters the structure though the gaps between frames, creating stripes of light and shade on the interior surfaces.
"Depending on the daylight the shadow play creates alternating patterns," said the artist. "From further distance the sculpture flickers in a moiré effect."
