Glass Pyramid
This pyramid was created with a face angle matching the angle of the sun at spring equinox for my location, 30.3575 degrees north latitude. There's not really any significance to that for the current project.
The project involves a possible game idea. Imagine a sort of treasure hunt, where items are to be found in various places in the pyramid. At the start of the game, each block making up the pyramid has glass walls on all sides. The player's job is to collect as many treasures as possible without collapsing the pyramid.
