Facebook's Paper photo tilt feature cloned in HTML5 before it gets released.
jt.ioThe [1] parallax tilt effect was out there for some time, so I don't think FB have implemented something new.
There is no parallax effect (AFAIK), the Paper's innovation comes from using stilt to scroll through the photo thus leaving the swipe gesture available to flick through pages/cards
Sure, but however - you can check the link; the plugin is about parallax on desktop, but there's tilt on mobile, which I think is pretty the same as on the FB Paper video. My thought is that it's not something totally new as UX.
