A container, including a number of angle elements. Each angle element includes a) a horizontal puzzle member including a male knob at one end and a female lock at the other end; and, b) a vertical member including a vertically extending male adjunct at one end thereof and a vertically extending female adjunct at the other end thereof, the vertical member being integrally orthogonally connected to the horizontal puzzle member. The angle elements are configurable, i.e. can be assembled, to form a container by: engagement of the male knobs of the plurality of angle elements with female locks of adjacent angle elements; and, engagement of the vertically extending male adjuncts of the angle elements with female adjuncts of adjacent angle elements. The container may include corner angle elements and additional types of angle elements such as intermediate angle elements, curved angle applications, L-shaped angle elements, etc.

A tier-on-tier multiple level jigsaw puzzle comprised of varying thickness and irregular interlocking pieces which, when assembled, form an image with visible surfaces in relief relative to the tabular surface. The puzzle is formed of a lower, base puzzle and an upper puzzle, which when combined have variable distinct surfaces and variable thickness with planar and/or textured surfaces to result in a raised relief 3D effect. The specific mix of individual pieces exhibiting variable thicknesses & distinct surfaces enhances enjoyment by adding strategic elements to puzzle assembly and optimizes the quality of the image.

A panel and a system for use in building a lightweight structure are provided. The panel, made of a film or a sheet capable of being curved or bent with fingers, includes a body in a geometric shape circumscribed by straight or curved edges, and at least one joint formation along the edge for panel connection. The joint formation has tabs separated by at least one gap. Each tab expands bilaterally and proximally from the body at its base, and each gap is positioned along the edge so as to accept the base of the tab. The joint formations along the edges of varied curvatures are alignedly, hingedly, and detachably interlocked with each other by twisting the panels with fingers to individually hook the tab at the gap. The panels are assembled into geometric structures having flat or curved faces.

A puzzle building block capable of changing light-emitting areas includes a building block board, a circuit board, light-emitting elements and building bricks. The building block board includes a plate body and connection portions. The connection portions are disposed on the top surface of the plate body. The circuit board is adjacent to the bottom surface of the building block board. The light emitting elements are disposed on the circuit board, and the light emitted from the light emitting elements passes through the building block board via the connection portions. The building bricks are fitted with the connection portions and shield the corresponding connection portions, thereby forming letters or patterns. Therefore, the light emitted from the light-emitting elements can form various letters or patterns on the top surface of the building block board. The present invention also provides a puzzle building block assembly including the above-mentioned puzzle building blocks.
