When LEGO MINDSTORMS was released - a hardware and software platform for programmable robots based on LEGO bricks - the talented dad seized an opportunity to merge his professional skill and personal past time by developing a model of an Airbus A380 incorporating the LEGO MINDSTORMS robotics into physical building blocks.
In 2009, the Brickman's creation won Best in Show at Melbourne's "Brickvention", and was later displayed at the LEGO Brickworld event in Chicago, USA.
The impressive construct caught the eye of a LEGO executive and McNaught was invited to become a LEGO certified professional.
Six months later, Ryan became the only person in the Southern Hemisphere to be recognised as a certified LEGO builder.

Today, he is involved with many LEGO company projects including building models for its offices around the world.
In 2010, McNaught launched his own Brickman business in Melbourne and now employs a team of passionate craftspeople who have built some of the world's most detailed and challenging LEGO constructions such as life-sized cars and the tallest LEGO model in the Southern Hemisphere.
The Brickman team have gone on five global touring exhibitions and created hundreds of models for display in museums, galleries and shopping centres.
Channel Nine confirmed Ryan is "thrilled" to take on the role of LEGO Masters judge.
The Brickman joins host Hamish Blake for the Nine network's latest project which premiered Sunday, April 28 at 7pm.
Adrian Swift, Channel 9's Head of Content, Production and Development said the Brickman's involvement is "major selling point" for the series.
