Finalist Competition Entry, Tunnel M, NoMa Parks, Washington DC: The tunnel interior rains with light – a fixed bright pointillist plane that turns a dark roof into a glowing field, radiating shifting curtains of light that cascade overhead like a set of waterfalls, guiding you along the sidewalk, down along the length of the tunnel. Four programmable patterns vary the intensity and placement of points within the LED field, creating a still effect of cascading waves, responsive to both automobile movement and the time of day.
