Modular wall systems

A modular wall structure comprising:

• (a) a first modular unit, the first modular unit having a first face defined by a first perimeter;
• wherein the first modular unit is a first triangular unit comprising a first frame, the first frame including the first face, a first side panel, a second side panel, and a third side panel, wherein each of the first triangular unit first side panel, second side panel, and third side panel project outwardly from the first face;
• and
• (b) a second modular unit, the second modular unit having a second face defined by a second perimeter;
• wherein the second modular unit is a second triangular unit comprising a second frame, the second frame including the second face, a first side panel, a second side panel, and a third side panel, wherein each of the second triangular unit first side panel, second side panel, and third side panel project outwardly from the second face;
• and
• wherein the first modular unit is operably, selectively, and reversibly coupled to the second modular unit;
• wherein each of the first modular unit and the second modular unit defines a truncated triangular pyramid shape;
• wherein one or more corners of the first modular unit and the second modular unit are truncated;
• and
• wherein each of the first and second frames comprise a plurality of ball couplings and stick connectors, wherein the plurality of ball couplings and stick connectors is configured to form a perimeter for one or more of the first side panel, the second side panel, the third side panel, and the first face of the first triangular unit and/or one or more of the first side panel, the second side panel, the third side panel, and the second face of the second triangular unit.
