A general-relativity-inspired visualization of a traversable wormhole throat: the tunnel wall bends and swirls light-like patterns the way gravitational lensing would warp space near a massive throat connecting two regions of spacetime. Under the hood it's a custom GLSL fragment shader animating hash-based noise, sinusoidal rings and a spiral term on a backside-rendered cylinder, layered with an additive-blended event-horizon rim glow and a 6,000-particle GPU point stream spiraling inward along an angle/radius/z model, all recycled procedurally as particles reach the mouth.
