Detailed Description

Simulates a TV static effect with noise, scanlines, and color variations.

The TVStatic class generates a dynamic and customizable TV static effect using a combination of simplex noise, gradient materials, scanline effects, and color overlays. The effect includes animation based on function generators and allows for layering multiple materials.
