More of a challenge than most, including myself, would expect. There are many types of pyramids, and for this project I have chosen the triangular right pyramid. Mainly to minimize the weight, as they are made of sheet steel, but for fabrication simplification as well.
The steel pieces will be suspended as invisibly as possible, and will have a window that has a material capable of catching some projection video. The design includes downward projected video, being projected onto a dome-like surface with the suspended inverted pyramids suspended over that surface.. .
