The framework that controls the geometry exists in an angle constraint between two 30-60-90 triangles. These triangle maintain their proportion as they rotate between near flat (1 degree) and near-vertical (89 degrees). This rotation ultimately contracts the six-triangle composite unit, further influencing the surrounding geometry.
The difficulty of this aggregation is not in making each triangle connect to the appropriate faces, rather in adequately constraining the movement to one axis. Accordingly, this model does not demonstrate the type of control necessary. Ideally, all contraction will occur along the xy plane so as to avoid absurd distortions seen in the video.

This next video demonstrates more development toward the semester-long screen project. Dimensional adjustments to this model can be made in x, y, and z (all through Parameter adjustments. Aperture size and orientation is controlled through the underlying sketch. All of the surfaces remain planar (with the exception of one!) in order to permit unrolled / sheet fabrication methods. See video below.
I am anticipating the use of global parameters (ie, point attractor) to orient the panels according to their relative position in space. When aggregated across a surface, each size modification parameter will incrementally play out and shape the unit. Below are possible opacity studies that demonstrate the parametric possibility of this particular module. All units maintain at least 2 points of connection to a structural grid beneath.
