```html Neon Hex ``` This creates a polished neon hex grid honeycomb with: - **Hexagonal grid** rendered across the full viewport using pointy-top hexagons - **Mouse-reactive glow** — hexes within a radius of your cursor light up with intensity based on proximity, fading outward smoothly - **Pulsing animation** — lit hexes gently pulse with sine-wave modulation - **Particle system** — colorful particles shoot out from the cursor path as you move, with velocity decay and fade-out, each having a bright inner core - **Cursor glow effect** — a radial gradient halo follows your mouse - **Hue shifting** — colors slowly cycle through the spectrum over time - **Motion trail** — semi-transparent background clear creates subtle motion blur - **Touch support** for mobile devices - **Responsive** — regenerates grid on window resize Save it as `modelname_neonhex.html` and open in any modern browser.
