An artwork called 'Obscure Bond 不可見的連繫' by Hong Kong artist Chun-kit Cheuk. It's one of the 13 artwork of a project 'Art@Harbour 藝術有理' at Tamar Park, Hong Kong Central Government Offices in Admiralty. It's one of the celebration events in town as Hong Kong celebrates the 25th Anniversary of the establishment of the Hong Kong Special Administration Region under the People's Republic of China in 1997. The project 'Art@Harbour' integrates science and art. This artwork is literally a form of 'street art'. People can observe gravitational forces inside molecular structures through AR.
