An icon I designed for a secret [still in-development] Mac App. I've had quite a lot of fun working on this one.
Check out the other sizes. I also made a black/white vector glyph for fun, and some bonus wireframes of the 3D model I used.
The hemispherical center bit is inspired by these old things, although I can't remember precisely where I've seen the grey version. Somewhere, I'm sure of that...
Hope you ❤ the icon. As always, feedback is awesome.
