Lawrence Yule's engineering background stood him in good stead on Monday morning as he helped two youngsters try out the components of an upcoming Hastings City Art Gallery's art installation.
About 50,000 pieces of white Lego make up The Cubic Structural Evolution Project - an installation that relies on the viewing public to build it.
The building blocks arrived at Hastings City Art Gallery last week, and after the Monday try-out are being stored until the exhibition opening on June 4.
The work is the brainchild of Danish artist Olafur Eliasson. It has been installed across the world including in Tirana, Albania, Oslo, Norway, Copenhagen, Denmark, New York and Queensland. In New Zealand it has opened in Auckland, Wellington and Dunedin.
More than 8000 people were expected to take part in its 12 weeks in Hastings, gallery director Toni MacKinnon said.
