The full scale installation would be supported by a grid that's attached to the trusses supporting the roof of the atrium, The lights would be encased by plastic tubes and are suspended between the grid and the triangles.  In the gif above, they're highlighted with a red color and their positions are determined by the parallel of the original surface with their length based on density of the triangles. 

The behavior of the lights in based off the video below with the slow-moving shifts in color and strong color palette intended to be bring notice to the shifts in color as they're viewed through the panels of the triangle. The dichronic film also serves to shifting the color identification as well as the varied angles of the triangles, warping passerbys' perception of the space above the triangles.
