Each of these artworks consists of a 22 metre diameter double-helix aluminium ring structure circling the columns over the eastern and western entries to ANZ Stadium.

Feathers, located on the eastern entrance of the stadium, consists of 96 large images of feathers depicting the diverse range of Australian bird life. The artwork combines the motif of the traditional sporting victor's laurel wreath with images from the natural environment of Homebush Bay - home of 140 bird species.

Skies, located on the western side of the Stadium, depicts Australian skies at different times of the day. The artwork  combines a reference to the traditional sporting victor's laurel wreath  with images of Australia's expansive skies. The spiralling band of aluminium is perforated unevenly, with solid metal representing clouds, and the perforated areas sunny days and a full moonlit night. The interior of the spiralling band is painted in the colours of the Olympic Medals: gold, silver and bronze.

The two companion works were created by New Zealand artist Neal Dawson to mark the entrances to Stadium Australia (now ANZ Stadium), the main arena for the 2000 Sydney Olympics.
