The medium that artist Nathan Sawaya uses couldn’t be more simple. As he says, it all starts with a brick. A humble LEGO brick.

But the stunning sculptures he creates from thousands of tiny LEGO pieces are surprising and delightful. And a new exhibit of them that opened here in Pittsburgh today, called The Art of the Brick, serves as a fittingly dramatic first exhibition at Carnegie Science Center‘s new PPG Science Pavilion.

The exhibit, which will be on display for the remainder of the year, features original pieces as well as re-imagined versions of the world’s most recognizable works of art, including van Gogh’s “The Starry Night” and da Vinci’s “Mona Lisa.” It also includes a gallery showcasing a multimedia collection of LEGO brick-filled photos produced as a collaboration with award-winning photographer Dean West.

And Pittsburghers will find a hometown touch: Sawaya has created a new, Steel City-inspired sculpture built specifically for this exhibition: the Three Sisters Bridges.

Visitors to the exhibit will also find a free-play and hands-on activity area called Science of the Brick, where they can create their own masterpieces.

Check out our photos from Friday’s grand opening below, where we took a tour with the ingenious LEGO artist and then get there to see these elaborate artworks up-close and create your own piece.
