These custom controllers from Microsoft are seriously awesome.
One of the #XboxE3 announcements this week has been the launch of the Xbox Design Lab, essentially a way for you to design your very own custom controller. Instead of having to go to a third-party you can get one directly from Microsoft in the crazy color scheme of your choosing.
They're based on the newest model controller that will ship with the Xbox One S, complete with Bluetooth for wireless connection to your Windows 10 PC, tablet or phone. At the moment only folks in the U.S. can order, but we will apparently hear more on an international rollout soon.
