1. A building block, comprising:
a body comprising an upper end, a lower end, and a plurality of holes configured to receive a back separable cover and a front separable cover, the body having a first side between a low point of the upper end and a high point of the lower end and a second side between a high point of the upper end and a low point of the lower end, a first extension direction along the first side being parallel to a second extension direction along the second side, the first side, second side, upper end, and lower end defining a substantially trapezoidal form;
a first main compartment;
an inner pass-through opening;
a first set of tapered lateral protrusions defining a first lateral dove-tail passageway; and
a second set of tapered lateral protrusions defining a second lateral dove-tail passageway,
wherein the upper end comprises a protrusion extending in the first and second extension direction of the building block beyond the upper end in the trapezoidal form,
wherein the lower end comprises (i) a slot and (ii) an intrusion, the intrusion intruding into the lower end in a direction of the upper end and removing a volume so as to accommodate the protrusion,
wherein the lower end and upper end are flanged such that the upper end connects with the lower end in the slot of the lower end, and
