There is a 29 ft. deep apron made of panels hinged to the state so they can be raised & lowered; there are three 65ft long 14ft wide plywood maskings which can be manipulated like Venetian blinds to project music out toward audience.

The edges of each panel featured hinges; internal hinges (along fold lines) connected two panels, while external hinges were at the edges of the panels and did not connect to other panels.
In Eq. (2) shear, panel zone, hinge offset, axial load and other secondary effects have been discarded in favor of simplicity.
Two types of substructures are examined: circular panels with hinge connections and circular ribs with rigid connections.
The thermal analysis model for the complex solar array is developed, in which all the honeycomb panel, simplified hinges, composite frames and yokes are taken into account.
The middle panel has hinges on both sides.
Many of the panels have hinged doors, the smallest about right for a white rabbit.
