Based on patented designs, these conceptual Xbox Cloud controllers give us an idea of what the real thing would feel like. Two controller-halves clip onto either side of the phone, turning it into a handheld gaming console, complete with everything you need to play Xbox’s signature titles. The controllers come in a variety of colors, just like the original Xbox ones, and feature all the keys, buttons, and joysticks, including BOTH the left and right triggers on the top!
