Built a procedural glitch texture generator (no AI, pure sin/cos math)

I needed glitch textures for a cyberpunk project and couldn't find anything decent that actually tiled properly, so I wrote a generator.

The approach is dead simple - it's all just sine/cosine wave functions with different frequencies and phase shifts. No noise libraries, no Perlin, just pure trig. Each texture gets a deterministic seed so you can regenerate the exact same output.

Made 8 different glitch types:

\- CRT scanlines (horizontal bands with subtle glow)

\- VHS tracking errors (those wavy distortion lines)

\- RGB chromatic split

\- Pixel sorting (the glitch art style)

\- TV static

\- Data corruption blocks

\- Hologram flicker

\- LCD deadpixels



Everything tiles seamlessly because the wave functions wrap at 2π. Generated at 2048×2048, comes out to about 200 textures total with variations. Released a free sample pack (10 textures) if anyone wants to try them:

The math is surprisingly forgiving - you can get away with pretty basic patterns and they still look convincing when applied to surfaces.
