Abstract: An interlocking block system is disclosed. The system includes a plurality of blocks which include projections on two lateral sides and receiving slots on two other lateral sides adapted to interface with the projections. The blocks further include interfacing members on top and bottom sides. Thus, the blocks can be connected both laterally and vertically. A passageway from bottom to top is provided, and a notch on the bottom side allows a cable to enter and pass through the passageway. Thus, various configurations can be built, and cables such as power cords or charging cords can pass up a leg of a built configuration. The sides of the blocks are configured to provide support to a block which is connected above and laterally to the first block, in various configurations, enabling stable lateral connections. Cap members interfacing with tops of the blocks are further provided to form a flat top surface.
