I have no idea what people would use this for, but i needed some ice cubes for a party poster im working on. I might use these for a wallpaper at a later stage, they are nice stock. Took a while to do.
Edit: changed the perspective on the cubes. added transparency.
Great icon! Would be cool to have a bunch of them: some smaller one, bigger one, some half-melting one.. So you could actually have your whole desktop filled with ice cubes. Something similar to KaYn's waterspot icons: [link]
