It's your last weekend to see "The Art of the Brick" at the Buffalo Museum of Science.

The exhibit, which combines art with engineering -- specifically Legos, opened this February.

Created by artist Nathan Sawaya, the traveling exhibit features "80+ sculptures...including a 20-foot-long T-rex skeleton and a recreation of Michelangelo's Statue of David," according to the Buffalo Museum of Science.

Sawaya, who used to be a corporate lawyer in New York City, is "the first artist to ever take LEGO into the art world." According to his website, Sawaya builds his creations using thousands and thousands of standard Lego bricks from 2002 on.

The exhibit closes May 5. The museum reminds patrons, "Tickets have designated entry times. We strongly recommend buying tickets in advance to ensure your preferred time slot."

Here's some photos from our visit earlier this month.
