His work for the 1988 World Exposition held in Brisbane Australia, the colourful Children of the World facade for the United Nations Pavilion, and the several 6 m high alphabet letter blocks that adorned the Entrance and Exit of the Australia Pavilion are largely regarded as playing a central role in the celebration and popular culture of Bicentennial Australia and were one of the most photographed works of art at the Expo. They have as part of the 30th Anniversary celebration of Expo 88 in 2018, been fully restored, including an interview with Ken Done.
