A modular wall structure can include a first modular unit having a first face defined by a first perimeter and a second modular unit having a second face defined by a second perimeter. The first modular unit can be operably and selectively coupled to the second modular unit. Base units can be provided to support the first and second modular units.

A method for laying a plurality of objects to form a polyhedron, the method including: determining a pattern for each of a plurality of courses constituting the polyhedron based on the type of the polyhedron and the frequency of the polyhedron; determining a unique group from each of the plurality of courses; determining members of the unique group and orientation of each the member of the unique group from the plurality of objects; and laying the plurality of objects as determined from the above steps to form the polyhedron.

A modular dome-like structure comprises a semispheric wall. A lowermost course of the semispheric wall is constructed using a plurality of springers. An intermediate course of the semispheric wall is constructed using a plurality of a first voussoir type. A second to uppermost course of the semispheric wall is constructed using a plurality of a second voussoir type. An uppermost course and third to uppermost of the semispheric wall is constructed using a plurality of a third voussoir type. The modular dome-like structure may have a cap constructed using a plurality of fourth voussoir type and a keystone or the modular dome-like structure may have an oculus. The modular dome-like structure may further include a lateral opening in the semispheric wall. The lowermost course and the intermediate course may be laid in a stretcher bond.

An immersive device may include reflective mirrored surfaces that form a perimeter of and bound a reflective chamber. Various geometric shapes of inner chamber such as platonic solids and objects of constant width are described that facilitate clusters of tessellations into infinite reflection unobtainable using other shapes. Specialized sizing and arrangements of the shapes allow for discrete full body observations of the tessellation clusters. One or more light emitting elements may be configured to emit light into the reflective chamber. A processing unit may be in electrical communication with the light emitting elements. A sound device may be in communication with the processing unit, and the sound device may be configured to output sound to a user within the reflective chamber. An array of sensors, such as: digital camera, microphone, and electrophysiological monitoring devices that may be in communication with the processing unit and are configured to change the experience of the user within the chamber depending upon the signals from the sensors on the user.

A method of erecting an acoustic shell for stage performances, the shell have frame defining a concave volume that is curved in two orthogonal planes and has an inner surface facing forwardly of a stage for a performance. A plurality of polygonal acoustic panels are positioned in the frame and spaced in rows and column along the inner surface, each panel having an outer acoustically active surface. The frame is formed of plural curved trusses each with a base for support on the stage and a peak. An oculus ring is connected to the peak of each arch and the bases of the arches are space along a bottom curve of the concave volume. The panels comprise plural adjacent blocks in rows and columns, each with a base and inner closed end, the length of each block being different for adjacent blocks.

An architectural building block system including a block having three side walls, each having an inside surface and an outside surface, the three side walls cooperate to form a triangular tube, the outside surface of each of the three side walls extending from the inner surface to the outer surface and the inside surface of each of the three walls is disposed substantially at right angle to each of the inner surface and the outer surface; and three channels, each channel disposed on one of the three side walls on the inner surface, wherein each channel extending from the inside surface to the outside surface of one of the three side walls and each pair of the three channels configured to receive a rebar.

A foldable structure comprised of hinged panel segments is provided. These segments are comprised of a first panel pair comprised of a first and second polygonal panel, and a second panel pair comprised of a third and fourth polygonal panel. Segments are bounded by a first boundary plane defined by two sides of the first panel pair, and a second boundary plane defined by two sides of the second panel pair, Measurement of a boundary angle may be taken normal to the intersection of the first and second boundary planes. As the segment is continuously folded between a first position and a second position, said boundary angle remains substantially constant during folding.

A portable theater includes a plurality of individual panels assembled together to form a theater enclosure, a plurality of audience seats installed within the assembled theater enclosure, and a projection screen mounted within the assembled theater enclosure. The projection screen has a partial toroidal shaped reflective surface configured to reflect, toward the plurality of audience seats, a moving image as projected by a projector.
