Render a stylized Dyson ring as a rotating wireframe with flickering starfield backdrop. The camera uses an orthographic projection so the ring keeps its scale while you yaw, pitch, and let it spin.

• Python 3.10+ (tested with 3.14)
• pygame (2.6.x) with SDL runtime
• numpy

Install the Python deps with pip:

python -m pip install pygame numpy

If you use a virtual environment:

python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\\Scripts\\activate
python -m pip install pygame numpy

From the repo root:

python main.py

This opens a window, animates the ring, and displays HUD text with the current Euler angles for pitch, yaw, and spin.

• Tesselates a ring into beveled curved box segments, seeds each face with randomized red city lights, and rotates everything in 3D.
• Projects with an orthographic camera, painter-sorts faces, draws edges in neon green, and overlays a glowing central star.
• Generates a saturated, twinkling background starfield for atmosphere.

• Drag left mouse button: yaw and pitch the view.
• ESC: quit.

• The HUD uses pygame.font.SysFont. If the requested typeface is missing, Pygame falls back to an available system font automatically.
• On macOS you may need to allow the SDL window to receive input if prompted.
