Everybody loves Lego. But if you have friends or family who think that all that plastic isn't eco-friendly, there's an alternative: earth blocks.

You won't find any vibrant primary colors, though: the sets tend to vary batch-to-batch depending on what goes into them, but they all retain the muted, natural hues of the raw ingredients. They come in just one shape and size, and you can buy a pack of 50 from the Guggenheim for $30. [Guggenheim via Design Boom]
