The device, called Centriphone, looks like a model airplane of sorts that holds your smartphone so the camera is always pointed towards you as you swing it around yourself. This lets you record some interesting footage with your iPhone 6 or 6s, and if you record in slow-motion, you’ll get a nifty bullet-time effect (seen in the video above). The design of the vehicle keeps your shots pretty stable and can be used to capture some pretty unique footage of whatever activity you’re doing. To build it on your own Centriphone, you’ll need a 3D printer or a way to outsource your 3D printing, but you can also buy a pre-made one from Vuignier’s web site (GoPro versions are available as well).
