PBS is airing a short film on Lego Art as part of their "Off Book" series. Most of you know Lego as a kid’s toy, but the little bricks we used to play with have evolved from game to art form. Watch this segment cut from PBS' Off Book Series. They talked to three LEGO artists who have made beautiful mosaics, amazing stop-motion videos, thoughtful sculptures, and have turned these tiny building blocks into a true artistic medium.
