related to his life experiences and sense of identity. He explained that, in his home country of Serbia, mosaic is an important art form in Byzantine culture. Unlike many other NEL artworks, the artists hand-crafted the work, with Milenko and his four assistants working on his thousands of miniature mosaic tiles. To emphasise the fusion of the artwork, the artists subtly adapted elements of each other's portions in their works. Delia's porcelains were integrated into Milenko's mosaics while his mosaic patterns were among the various spiral and elliptical shapes of Delia's tiles. Some patterns and colours are repeated so that the different parts of the work share a common theme. Reflecting on the artwork, the Prvackis said that the project was a learning experience for them that required stretching their artistic thinking within the structural requirements while meeting the needs of commuters. Milenko added it was a "rare pleasure" working with his wife on the project. Universal Language Another artwork, Universal Language by Sun Yu-Li, consists of 180‑floor tiles with various motifs distributed across the station. These tiles, accompanied by 14 glass plates positioned at various places in the station, act as wayfinding icons and guide commuters through the complex interchange via six different routes. These symbols lead to a large floor mosaic and a glass mural displayed at the centre of the station at Basement 2. The mosaic and mural incorporate the motifs used on the tiles. The artwork, which reflects Sun's background as an architect, was created to address the station's complex layout. Sun also wanted his work to be enjoyable to commuters. Derived from the station's role as a "gateway" for arts and culture in the area, he hoped to explore an "objective" and "pure form of expression" that connected to all cultures. This led Sun to develop a "universal language of symbols" based on prehistoric art. The hunter, dancer, rider, animal, fish and bird were used as different sets of symbols for each of the six routes. The initial concept was for the figures to emerge over time after accumulating dust and dirt. However, to improve the visibility of certain complex shapes, the figures were chemically treated. Man and Environment The CCL station features a wall relief, Man and Environment by Baet Yeok Kuan. The work consists of 36 white gypsum sculptures across the three columns supporting the CCL station. These sculptures depict unusual textures the
