I just made and released a startorb, heavily based on yours, with slight differences. I have credited you and linked to this thread in the description. If you have problems with me releasing a start orb similar to yours, lease say so and I will delete the thread.
The main difference between mine and yours is the glow that appears above the orb on hover, just like the systray icons.
I have a version with the glow to, but I never released it, but good and observant of you to add the glow to, so it becomes even more like the systray icons. (But I have never really liked the glow effect there)
Have anyone a Bluetooth icon that follows the same theme? It would be nice if ever program that runs in systray where white.
