3DS systems. That's right, updating your 3DS on Sunday will beam OK Go's 3D video "White Knuckles" right to your home screen.
The video will be deleted with the following update, so savor its three-dimensional dog-training amusements while you can. If you want a preview, you can watch the video in stupid, revolting 2D after the break.
Side note: Our friends with Japanese 3DS systems got a similar update, but with a video of Koji Kondo and some other Nintendo folks playing the Super Mario theme. Feel free to argue about who's getting the better end of that deal.
