on the third floor across a huge open window. It is suspended from the ceiling at high. The artwork is made up of painted geometric shapes with many vibrant colors, some having a solid color while others have a tie-dye effect painted on them. The artwork is connected together in a horizontal diagonal with a circular shape in the middle. The circular middle is red on the outside and underneath is painted with many different colors in a tie-dye effect. It also has small blocks under it painted in solid colors of red, orange, blue, and yellow. Attached to some of the small blocks are triangular blocks. Jamaica Center Station Riders, Blue (1991) Located at the Jamaica Center train station (E,J,Z) Jamaica Center Station Riders, Blue is a large aluminum sculpture mounted high outside on a wall above one of the entrances. The Metropolitan Transportation Authority Arts for Transit project commissioned the work in 1991. It is made up of geometric shapes painted in solid primary colors (red, yellow, blue). The shape of the overall sculpture is circular, with the outer part being blue while the inner parts are red and yellow. In the artist's words, the work "calls to mind movement, circuits, speed, technology, and passenger ships...the colors used in the piece... refer to colors of the respective subway lines. The predominant use of blue provides one with a visual solid in a transitional area that is near subterranean."
