Came across this link that shows Afterburner skins which I don't think are already shown here. I like the Nvidia Flat Skin Big Edition myself. Click me
I like those skins too. BTW, Airframe skin was a reason why I added new skin composition modes to AB 4.x. This skin window shape contains a lot of non-rectangular areas (more than any other existing skin) so it is rather slow when using default traditional skin composition mode. With layered skin composition modes it is rendered much, much faster.
