It's a classic toy for kids aged four years old to 99 years old, but one man's made it an art form, and is bringing his sculptures to Auckland.
When Ryan McNaught plays with Lego, it's serious business. He's the southern hemisphere's only Lego-certified professional and one of just 14 worldwide.
A whole bunch of his large-scale models have been gathered together and are in Auckland for the Brick Man Experience.

It's the culmination of more than 5000 hours of work over several years, containing more than 5 million Lego blocks.
The Brick Man Experience boasts the world's largest Lego flower with 100,000 bricks, painstakingly assembled brick by brick over the course of 400 hours.
More than 120,000 bricks were used to build the 6m tall Apollo 11 rocket.
And there's a Ferrari 250GT -- because he couldn't afford a real one, so why not build your own?

While McNaught isn't going to be building anything at the exhibition, there is an opportunity to be a part of his work.
Visitors can sign a brick which will later be used as part of a unique sculpture.
While in Australia, McNaught constructed a crocodile, kangaroo and shark sculpture made from signed bricks from the Sydney, Melbourne and Brisbane shows respectively.

The Brick Man Experience opens in Auckland on Friday. Just be careful not to knock anything over.
