In what seems to be a convention tradition now, LEGO had a giant mural that booth visitors can help build. Since each day of the con had a certain theme, the 30′x7.5′ wall was divided into four even sections with each section dedicated to a day’s theme. The baseplates comprising the wall had a numbered grid printed on top corresponding to 6×6 stud plates. The 8×8 plates were also printed with colors where the matching 1×1 bricks are supposed to go. Once the 6×6 plate is complete, it is then hammered onto the wall.
