Photos: Going for the Lego gold

Arthur Gugick, a high school math teacher from Cleveland, made this Lego face during the first round of skill tests at the Master Model Builder competition in Legoland California.

On Tuesday, the finalists will square off in a two-hour "build-off" in which each will be tasked with building a model based on something they think would fit in well at the theme park.
