Lego makes storage containers that click together like standard bricks (Amazon), coming in a range of sizes and all the classic lego colors, from single-nodule pencil cups to four- and eight-nodule boxes.
They suggest using it to store normal lego bricks, which makes me want a range of miscroscopic legos that may be stored inside the normal ones, with these tiny ones concealing a further inner layer of quantum-scale legos.
