Join your fellow building enthusiasts February 18 and 19 at the downtown library for friendly competition, performances by Mr. Bond and the Science Guys, and lots and lots of LEGOs. Register for the contest by clicking here, get all applicable rules and details here, and then start building.

All entries for the contest must be original creations, of course, but check out the books below for inspiration and LEGO history to get your wheels turning.

And LEGO love isn't limited to February at the library, there are building clubs and programs all year at branches throughout the city, so make sure you're in the LEGO loop by checking out these NPL events.
