A collapsible play structure having a collapsed configuration and an opened configuration comprises: a left panel having a back surface, a front surface, a horizontal axis, and a vertical axis; a left fold out structure coupled to the left panel, the left fold out structure comprising one or more members rotatably coupled to the left panel to be rotatable about an axis parallel with the horizontal axis of the left panel; a right panel having a back surface, a front surface, a horizontal axis, and a vertical axis; a right fold out structure coupled to the right panel, the right fold out structure comprising one or more members rotatably coupled to the right panel to be rotatable about an axis parallel with the horizontal axis of the right panel; and a center panel having a back surface and a front surface, the center panel rotatably coupled to the left panel and the right panel in an orientation that aligns the vertical axes of the left panel and the right panel in a parallel alignment, wherein, in the opened configuration, the left fold out structure and right fold out structure are coupled together by at least one releasable joint.

A curvilinear tetrahedral enhanced building block may be formed. The block may include sigmoid or reverse sigmoid curve edges, and may include curved vertices. The shape various planes or vertices of the block may be selected or adjusted to exert a force against a surrounding viscous medium. The block may include a conductive element configured to generate an electrostatic field, and may include a magnetic element configured to generate a magnetic field. The block may be configured to conduct electricity to a surrounding dielectric fluid, and the block's generation of a magnetic field may induce magnetohydrodynamic motion within the dielectric fluid.

A vibrating toy assembly that can travel along a surface in an unpredictable pattern. The toy assembly is powered by a vibration mechanism. The vibration mechanism has a motor and batteries that are held with a housing. The vibration mechanism is placed into a hollow casing. The hollow casing defines an internal compartment. Once activated, the vibration mechanism vibrates and moves the casing. This causes the overall toy assembly to move in random patterns.

A folding toy theatre with characters that move using just one finger, comprising a theatre surround with side flaps which fold backwards allowing it to stand upright, the front face has a cut central aperture and a slot cut out at its bottom face edge. The characters have a long forward flap from the base of the body to action it and two flaps at the left and right sides of the body which fold backwards to keep the character upright. The character is placed inside the theatre surround the long forward flap passes through the bottom face slot of the theatre surround so the character can be moved from the front of the theatre. The theatre surround can have slots in its side flaps, a tabbed background can be added or the side flaps have a slot and latch to join directly.

In accordance with the present invention, a stand-alone pop up assembly and method for making the same is provided comprising a plurality of wall panels connected with an internal base. A roof structure is provided and a roof interface component for attaching the roof to the structure. The assembly is moveable between a first position being substantially flat into a one dimensional structure and a second position enfolded into a three dimensional structure by manipulating the outer structure and the internal base. The roof interface component may swivel into place during the movement to the three dimensional structure, thereby positioning the roof structure over the upper portions of the first and second panel walls or, alternatively, a sliding feature is provided with a tab from the roof inserted into a slot at the top of one of the panel walls, thereby sliding the roof into position.

A method of forming a foldable backdrop through a series of folds placed in a single sheet of foldable material selected for the backdrop. When the final step is taken of pushing a first bottom corner of the sheet under a first mountain fold and pushing a second bottom corner of the sheet under a second mountain fold, a base is formed out of a bottom half of the sheet. A tension in the sheet will force the top half of the sheet into a vertical position perpendicular to the base.
