Singaporean artist Lee Wen made Ping-Pong Go Round , an interactive art installation. It's a modular ping pong table that allows several people to play at the same time. The set is portable, so he's taken it across southeast Asia and Australia, inviting people to play this loopy variant of the game. Most recently, he exhibited it at Art Basel Hong Kong.
