To see the Denver Museum of Nature & Science’s newest big animals on display, visitors don’t need to roam their expansive Wildlife Halls. Rather, artist Sean Kenney has dozens of animal sculptures up for viewing — all made entirely of Lego bricks – 1.5 million Lego bricks to be exact.

Kenney’s exhibition, “Brick Planet: A Magical Journey Made With LEGO® Bricks,” includes sizable sculptures of flora, fauna, cityscapes and more through a meandering room, taking visitors through various immersive ecosystems.

The exhibit, one of several of Kenney’s, focuses on the natural world and its animal inhabitants, making it a ideal fit for the museum’s educational mission.

“He was inspired by nature and also sees himself and his family in some of the pieces,” museum program coordinator, Kelsi Cowan, said. Many of the sculptures feature depictions of animal families, including a polar bear mother and cubs comprised of more than 130,000 bricks.

Kenney’s sprawling exhibit doesn’t shy away from environmental issues facing his sculptures’ wild counterparts, either. It features an homage to the bicycling lifestyle, with a green bike towering over black cars and a disappearing rhinoceros, meant to symbolize the species’ steep decline across habitats.

“It’s just stunning and wonderful that someone could create all of these,” museum guest Honey Goldberg said while stopping to admire many of the pieces at length.

The museum also added a Colorado spin, with a graphic designer remaking some Colorado icons like Red Rocks and Black Canyon of the Gunnison in pixelated-brick posters. Other staff added educational components to examine the animals on display places in their respective ecosystems.

The exhibition, included with general admission, is on display into early May.
