Terry Fugate-Wilcox, proposal for Melbourne Landmark Weathering Sculpture, ca. 1980–82, materials, support, and dimensions not known (artwork and photograph © Terry Fugate-Wilcox)

The text at upper right reads:

This is a sculpture for the future. It changes with the passage of time and becomes more colorful and more beautiful with age.

Each concrete panel ends with a bar of metal, or other material, which gradually colors the concrete with each rainfall.

The tetrahedral structure, truncated by great panels of glass, is meant to be enjoyed from the inside, as well as from the outside.

This is a multi-use structure, as well as a work of art. It can house an observation deck, sports arenas, a skylight restaurant, art galleries and shopping arcades, for examples.
