Custom Traktor interface

I'm not sure that you guys have seen this little plug-in yet. But it's pretty cool.
It's call "Nocturne"
It's a little plug-in that allow you to customize your desktop color. I found that it really useful for Traktor's user especially, when you Dj in a low light place and the brightness of the screen is poking your eye. You can customize the interface's color in many different ways for example : invert color, black and white, HUE adjusting and specific color shade.
Check it out, I can only post one example. I tried screen capture different interfaces setting but It's not showing the customized color (not sure why)
