Vicissitudes depicts 26 children of diverse ethnic backgrounds holding hands in a circle, representing unity and optimism. The piece took six months to make and weighs around fifteen tons.

possibilities of a sustainable future, portraying human intervention as positive and affirmative.
“What I’m most interested in is the idea of change and process,” he explains. “It’s meant to mirror our lives. In the same way that children are meant to absorb their surroundings as they grow up, these under­water children will also be heavily influenced – they’ll take on the patina of their environment as they grow and change over time.”
