the 50-metre long tunnel in central copenhagen leads to a recycling centre. the project manager, susanne felland, from the amager ressource center explained that the objective was to "transform a dull, grey entrance into an experience beyond the expected". the wall paintings inside the tunnel are illuminated and transformed with hansen's 24 led spotlights which create dynamic scenes running in a 20-minute loop. hansen explains that the lights can be programmed and each beam modified for brightness and colour.
