The audience has been turned into the artist at the Dunedin Public Art Gallery this week.
An exhibition constructed of Lego blocks has been providing inspiration for the young and nostalgia for the old.
The Cubic Structural Evolution Project is an installation by Danish artist Olafur Eliasson (47) which requires gallery visitors to complete the work using their own imaginations.
The work is centred on a table piled with 150,000 white Lego pieces, which the audience then uses to construct an evolving miniature cityscape.
''The public response has been huge. We're absolutely thrilled,'' DPAG marketing manager Tim Pollock said yesterday.
''It hasn't just been the kids enthralled; the adults have been, too. We've had lots of kids running around, but a lot of them have been running around getting bits of Lego for their dads.''
The gallery also hosted talks by Christchurch Lego architects Centuri Chan and Christoph Bartneck at the weekend.
The 2004 work is on loan from the Queensland Art Gallery until August 3.
