Blind Spot
Runko Housing Co-Operative, Helsinki

Aluminium parabolic reflector with concealed supporting structures, stainless-steel frame, custom-made LED
lights, cabling, industrial computer
A large parabolic reflector, four metres in diameter and painted matt white, was embedded in the suspended
ceiling of a two-storey gateway leading to the inner courtyard of the housing co-operative. The surface of the
reflector was painted matt white to give as even a reflection as possible. Fitted around the reflector, but
hidden by the suspended ceiling, were 24 vertical narrow-beam spotlights controlled by a computer. The program
controlled each spotlight individually, adjusting the warmth and intensity of the white light, and taking the
length of the day into account. The tone and brightness of the light on different sides of the reflector
changed slowly, almost imperceptibly, giving an impression of movement and making faint patterns on its
surface.
