If you live in New York state, you ought to see this interactive installation on the Westchester County side of Tappan Zee Bridge, which spans the Hudson River between Nyack and Tarrytown. 

The lighting structure, known as ‘’Current’’, is comprised of 12 triangular steel arches standing firm on a concrete foundation, all of which are lined up alongside each other while gradually decrease in height.

It is these arches that help create the dynamic lighting effect this sculpture is known for. Each of its arches is fitted with an iridescent glass fin on its apex which helps refract sunlight and create shadows during the day. While at night, the lighting structure shines through its integrated LED lights that produce a white glow after dark. 

Its modern motion sensors help detect the movements of the passing pedestrians, drivers and cyclists, triggering enchanting light animations as a result. The installation is sort of similar to a clock's chime in the way it plays a different light animation at the start of each hour of the day.

When asked about the inspiration for the structure, artist Wing-Zi Wong said that the Current pays homage to the legacy of the Tappan Zee Bridge which has been a historic primary connection point spanning the Hudson between the two counties north of New York City.

She further added, "Its name was chosen in reference to the ebb and flow of river currents on the Hudson River, as well as currents of light and currents of time. In a way, the work is a dynamic and interactive sculpture that celebrates transformation."
