Perhaps how a cement ping pong table looked has almost gone from our memory. It was an object with an unassuming existence: Made of cement, it was rugged, cheap, and would have weathered a lot of rain and storms. Compared with the ping pong tables in modern sports centres, it lacked bounce, and was not standard in size.

As the artist remembered, the cement ping pong table only attracted unskilled, pint-sized players to play a double game, with an occasional adult to give pointers on the side. Installed in some covered area in public housing estates, it was the trusted companion in the childhood memory of many, or even of an Olympic player or two. Now as a sculpture, it is a tangible form of community participation; as a sports facility, it has shaped part of the history of Hong Kong sports development.

With each fast-growing community development comes a stadium with the latest facilities. It's time for the old-style cement ping pong table to bow out. But the artist has salvaged one from an old public housing estate and installed it outside the Tiu Keng Leng Sports Centre. It is not only for memories' sake, but also a tribute to the past.

The members of the team are Hong Kong artists, graduated from the Academy of Visual Arts, Hong Kong Baptist University. They try to achieve community building and community participation through art installations in different areas. They also pay attention to local cultural development.
