In one embodiment, an article of manufacture includes a plurality of nestable, identically sized building blocks, each block having at least one inward-slanting side wall connected to a top surface of the block at an edge of the block, wherein a first block defines a hollow interior space adapted to receive a second block in a nested configuration. One or more of the blocks have one or more recesses on the top surface that are each designed to receive a portion of the bottom edge of another block, thereby providing increased stability for non-nested configurations. A recess may have a curved shape that can receive a curved portion of another block at different angular orientations of the blocks. The recesses may engage another block's bottom edge in a non-interlocking manner or in an interlocking manner.
