Accents: metallic red
Greeting: "Hail to the king, baby" (spoken by Ash in Army of Darkness)
Engraving: "Be Different"
Wallpaper: something abstract, black & red
The color combo just because it would look great. Greeting is a double win, as I love AoD and it's also like saying the Moto X is king. The engraving is poking fun at Apple; the Moto X can be greatly customized, so you can be different and not just "think different"
