To commemorate the 30th anniversary of Star Wars: Episode V The Empire Strikes Back, LEGO Systems, Inc. and Lucasfilm Ltd. summoned the force of LEGO and STAR WARS fans to participate in what was a three-day collaborative build of an eight-foot tall, 15-foot wide LEGO mystery mural to benefit St. Jude Children’s Research Hospital. The mural was constructed by attendees of Star Wars Celebration V and a LEGO Master Builder, George Lucas himself even stopped by to lend a hand. Check out the video released by LEGO below.
