Union Square Park
Project proposal 1995
The temporary project “Union Square Park” is a reenactment of a scientific principle. The concept of the site-specific installation is the delineation of time through spatial line drawings. The project aims to visualize the boundaries of the park via the construction of four gnomons, which cast a shadow play across Union Square. Each column is located at one corner of the Square. Simultaneously, lines are projected and drawn on concrete throughout the day.
The four gnomons that project individual shadow lines during the day are transformed to luminous columns at night, which are connected through projected laser lines. A spatial grid is drawn by means of the architectural application of the laser beam, like a pencil sketching the entablature in mid air.
The distance from North to South is approximately 550 feet between the gnomons. The distance from East to West is approximately 350 feet. The measurements of the four boom sections are each 54 inches by 60 inches wide and 80 feet tall. The white fiberglass cloth wrapped around the towers is lit from within. The texture of the fabric lends its glowing sheen; the four boom sections form the pillars of a luminous architectural structure.
In the dark, light is used to draw the outline of a cuboid, which surrounds the park. Traffic going south on Broadway passes through the embedded space, moving between the salient pillars. It is the juxtaposition of shadow lines, projected by the gnomon through the sun, which delineate time during the day ad luminous line at night, which delineate space.
