The MLC Centre in Sydney CBD was the tallest building outside of North America in 1977. Designed by architect Harry Seidler, it now dons an Ephemeralist Table by Public Outdoor Ping Pong. The designer  table is a permanent feature in the courtyard (outside the foyer) for visitors, workers and shoppers to use at their leisure. Feast your eyes on the matt black and yellow colour palette (to match an existing sculpture) and the Buckminster Fuller frame.
