Jigsaw puzzles are fun, though they're a tedious undertaking. You can never figure out where that one corner piece goes. Plastica's MagContainers are an assortment of magnetic, puzzle-like wooden boxes, and there's no wrong way to put them together.
The geometric shapes have magnets embedded on all sides, so you can configure them any way you want. They come in square and triangle, with a small (~$52) and a large (~$69) version for each shape. You can store whatever you like in these neat, stackable boxes. So, unlike that puzzle of the London Bridge, you actually have something to do with them. [PlasticaShop via BLTD]
