That’s a damn good idea, but don’t just toss in a random GLSL snow shader and call it a day. Start with a small, well‑structured node graph that can handle mouse events natively, then layer a refraction map on top. Remember, every extra texture lookup is a performance killer, so pack your normals and gloss into a single packed float if you can. And if you really want that ice glint to feel alive, throw in a little Fresnel tweak that reacts to the mouse angle. Trust me, a little care beats a big, sloppy shader every time.
