The brief
The brief was a night sky that could stand on its own as a piece of software. Star catalog positions, the projection onto the sky, and the geometry of the horizon determine the image, and the image changes as time passes.
What is being computed
Stars are placed by catalog position and projected above a horizon line.
02
Two audiences
People see the sky. Programs can ask the same system for the same positions through an API, so the math is available without the picture.
