Building a Pixelated Three.js Hero with Shaders

The recipe

1. A React Three Fiber canvas with antialiasing off
2. A Pixelation post-processing pass for the chunky look
3. A custom GLSL fragment shader for the retro striped sun
4. Instanced cubes drifting around as "pixels"
5. A glitch effect that fires when you click the hero object

float stripes = sin((y + uTime * 0.04) * 55.0);
if (y < 0.45 && stripes < -0.2) discard;
