Tree huggers come in all shapes and sizes, but did you know that they even come in multicolored LEGOS? In honor of Earth Day, LEGO artist extraordinaire Nathan Sawaya crafted a quirky series of Hugman sculptures wrapping their arms around park trees in New York City. The life-size LEGO sculptures are built with approximately 50,000 recycled bricks, each individually signed by a visitor of The Art of the Brick exhibition at Discovery Times Square.
