With this one I just played around with some metallic materials. The main thing I tried to figure out was how to get realistic looking reflections without having to model a whole environment. I used a texture with very fine details as background and for the environment map.
Since this is some kind of robotic drone i think these binary numbers were a good choice for the background.
