Show HN: I made an online fan because the whether is hot

When the summer sun decided my apartment should double as a sauna, I did the only logical thing a dev could do: built a WebGL fan instead of buying a real one. Now you can spin it too — and hopefully cool down your CPU while you're at it.

Because heat makes us do weird things. Some people buy air-cons, others invent ice-cream soup. I cracked open Three.js and Vite to summon a digital desk fan. It might not drop the temperature, but it does look cool, has whirring blades, and gives you full power over its destiny.

• 🌀 Real-time 3D fan powered by Three.js & GLTF.
• 🛞 Built-in animation — watch those blades spin like your favorite coffee after 6 espressos.
• 🎛️ GUI sliders & buttons to tweak speed, rotation, height, and scale.
• 🌈 Texture-rich model (no bland plastic here).
• 🚀 Deploy-ready with Vite + GitHub Pages.

Open http://localhost:5174 and bask in the virtual wind.

(Pro tip: press ⏻ to power on, then crank the sliders — but mind your hair!)
