COLTC's colorful layouts have been shown throughout the state of Ohio and well beyond. Over the course of the last year, COLTC has displayed eleven layouts varying in size from 90 to over 600 square feet. Most of the displays were done as part of train shows, but displays have also been held at a shopping mall, the Cleveland Science Center, COSI Toledo and as far away as Belleville, IL and Washington D.C.
Through these shows, COLTC has become known for its relatively large and unique LEGO® creations; quite a few of their buildings exceed 5 feet, and took as many as 150 hours to build. The creations by the club members vary from boats to chickens, and from spaceships to forests. A single creation can consist of only a handful of individual pieces to as many as 100,000 bricks. Some of the creations are scaled replicas of existing buildings, while other models are purely fantasy-based. Examples of scaled model replicas range from old steam trains to Columbus skyscrapers such as the LeVeque Tower and the Huntington Banks building that are built in 1:100 scale.
