I was looking through Microsoft's Vista site today when the icon for "Community" in their nav bar jumped out at me. It's OmniWeb's! Well, not exactly, but close enough. Same perspective, very similar color palette, same lighting point. Granted their missing the terrain relief and weather effects, but still!
