This is my first try on a custom controller. While it has quite a few flaws, from which I've learned a lot for when I'll do another, it didn't turn out bad, I think.
I went with a black-golden design inspired by Deus Ex: Human Revolution.
It's a first (or early at least) generation XBOX 360 Controller. I completely repainted the case, replaced the green LEDs with yellow ones and also replaced the worn out grey thumbsticks with newer, black ones I got from another controller.
