This version of the classic Snake game simulates how massive objects create wave-like distortions in spacetime:

1. Wave Propagation: Each grid point calculates its distance from the snake's "gravitational source"
2. Wave Amplitude: A cubic falloff function determines the intensity of the gravitational wave at each point
3. Spacetime Ripples: Grid points are displaced toward the gravitational well, creating visible waves in the fabric of space
4. Wave Interference: As you move, the gravitational waves propagate outward, creating dynamic, flowing distortions
5. Gravitational Redshift: Colors shift from cyan to red-orange based on wave intensity - simulating how light frequencies change in strong gravitational fields
