Welcome to the new site.
This is a placeholder first post — the interesting part is what's rendering behind the home page: a real-time Schwarzschild black hole. Every frame, the GPU integrates light rays backwards from the camera through curved spacetime:
a = -3/2 · h² · x / |x|⁵
That single acceleration term is enough to produce gravitational lensing, the photon ring, and the famous "hat" — the far side of the accretion disk bent up and over the event horizon.
