For the interactive children's museum, the 'Un-Museum', in the sixth floor (above), the designers consciously opted for a different lighting concept: flush-mounted Hi-trac tracks either carry Pollux spotlights on track inserts or are used as fluorescent luminaires.

The light in the entrance area (to the right) is composed of a diffuse component from opaquely covered trenches of light and directed light from Gimbal recessed ceiling mounted directional luminaires.
