There are some new stack and lock bricks on the scene. Lego bricks are classic toys, but there's no denying these re-envisioned "Earth Blocks," made partially from recycled materials — coffee beans, cedar sawdust and cedar bark — are a fantastic idea.

The bricks combine the natural materials with polypropylene to keep them rigid, and retain the same muted colors as the coffee and cedar that are used to make them.

Michael Hsu reviewed the bricks in Saturday's Wall Street Journal, and notes: "Earth Blocks are softer around the edges than the classic toy. As a result they don't snap together as tightly as LEGOs do."

The bricks come in one size (1 ¼" by 5/8" by 5/8") and look like this:

So the building is pretty basic at this point, but who knows how this toy will evolve?

Choose from one of the building materials — coffee beans, cedar sawdust or cedar bark. Price: 50 bricks for $30
