A Special Thanks
To the company HeavyDutyTarps which helped us build the augmented reality sandbox, thank you! Taking a closer look at the concept, the tarps encapsulate the sand to help prevent spills as well as cover to minimize dust from dirtying the sand. Since the sandbox first launched, the tarps have withheld the quality test and are still in great condition.
Here are some pictures of the bottom (on the left) lining and top cover (on the right):
