This was a project we did for Muziekgebouw Eindhoven. When people walked between the camera and wall, we'll put them to a stop and let them know we caught their shadow. The shadow has been converted into light and is displayed inside the building on a big 13m x 3,5m LED-screen. We would tell the person, who's shadow had been caught, half of their body is already in the building and they can take a look if they recognize themselves.
