Focus on this artwork and analyze the Description.
Housed inside the bridge's original watchtower (or bridge tender's house), each of the six windows has a group of reflective, dichroic acrylic kaleidoscope cones that feature abstract reflective floating surfaces of color and light.  The bottom of each cone has a mirror and a light that assists in producing a reflection. Each angle produces a different hue which emanates from the windows, visible from the bridge, the Washington Metro and the Potomac River, but in compliance with U.S. Coast Guard regulations, not allowing it to distract drivers on land or water. Overall, the piece sends out "thousands of glimmering colors in six directions where a drawbridge once sat."The kaleidoscopes consist of panels of clear and reflective acrylic material. The reflective and dichroic panels are clipped and bolted to the masonry window sill of the structure. The acrylic was chosen due to its sturdiness as a shatterproof, heat resistant, fire retardant product that also resists sunlight fading. Three fiber optic illumination boxes with a central halide fixture are installed with multiple fiber optic cables that serve as lighting sources for the kaleidoscopes. They are secured with steel beams and platforms, which also serve as  a rotating table for the lights.
